Time Flies or Flys? Meaning and Examples 2026 

Have you ever looked at the clock and wondered where the whole day went? One minute, you’re laughing with friends, enjoying a trip, or watching a movie. The next minute, it’s already time to go. That’s when people say, time flies when you’re having fun. But wait! Is it flies or flys? This small spelling mistake can confuse even confident English writers. The good news is that one simple grammar rule can help you get it right every time.

If you’re searching for the correct spelling of time flies or flys, you’re in the right place. We’ll explain why flies is correct, what it means, and when to use it. You’ll also see easy examples, common mistakes, and a simple memory trick to help you remember the rule. By the end, you’ll feel more confident using the phrase in everyday conversations and writing.

Flys vs Flies: The Quick Answer

Are you unsure whether to write flys or flies? You’re not alone. This common spelling confusion happens because English uses different rules for words ending in y.

In standard English, flies is the correct spelling for the plural of fly. It also works as a verb when someone or something moves through the air.

• Flies: The kitchen has several flies.
• Flies: The bird flies over the trees.
• Flys: Usually an incorrect spelling in everyday writing.

For example, imagine you’re writing an email about insects in your kitchen. You should write, There are five flies near the window.

Remember that flys may appear in a proper name or a specialized context. However, don’t use it as the regular plural or verb form.

The same spelling applies in American English and British English. When in doubt, choose flies.

What Does “Flies” Mean?

The word flies has two common meanings in the English language. It can name more than one insect or describe an action.

As a noun, flies refers to small flying insects. As a verb, it describes someone or something moving through the air.

The meaning depends on how you use the word in a sentence.

• Noun: Flies gathered around the fruit.
• Verb: The airplane flies across the country.
• Expression: Time flies when you’re having fun.

These examples show why context matters. The spelling stays the same, but the meaning changes.

For English learners, recognizing the noun and verb forms makes writing easier. It also helps you avoid common grammar mistakes in school assignments, emails, and blog posts.

Flies as the Plural of Fly

A fly is a small flying insect. When you talk about more than one, the correct plural form is flies.

You might see flies around food, garbage, or outdoor spaces during summer. Farmers may also deal with flies around livestock and farm buildings.

Here are a few simple examples:

• One fly landed on my sandwich.
• Two flies buzzed around the kitchen.
• Several flies gathered near the window.
• The housefly is a familiar flying insect.

Notice the spelling change from fly to flies. You don’t simply add s to the end. Instead, you change the y to ies because the word ends in a consonant followed by y.

Conversation example:

“What’s buzzing around the fruit bowl?”

“Those are flies. Please cover the fruit.”

This plural form follows standard English spelling rules.

Flies as a Verb

Flies is also the third-person singular form of the verb fly. It describes the action of moving through the air.

Use flies with subjects such as he, she, or it. With I, you, we, and they, use fly instead.

Subject	Correct verb form
I	fly
You	fly
We	fly
They	fly
He	flies
She	flies
It	flies

For example, a pilot flies an airplane, an eagle flies over a mountain, and a flag flies above a building.

Conversation example:

“Does your brother fly to Chicago often?”

“Yes, he flies there every month.”

This verb form follows subject-verb agreement. Remember the rule when writing sentences about birds, pilots, airplanes, or even superheroes.

What Does “Flys” Mean?

The spelling flys looks reasonable at first glance. Many English words form plurals by adding s, so it’s easy to see why people make this spelling mistake.

However, flys isn’t the standard plural of fly. It’s also not the correct third-person singular verb form in standard English grammar.

For everyday writing, use flies when talking about insects or describing something that flies.

• Incorrect: The bird flys over our house.
• Correct: The bird flies over our house.
• Incorrect: There are three flys outside.
• Correct: There are three flies outside.

You might see Flys in a brand name or proper name. Specialized uses may also exist, depending on the context.

When writing an email, school assignment, or blog post, choose flies for the ordinary noun and verb forms.

Technical Uses of Flys

You may occasionally encounter Flys in a company name, product name, or specialized document. However, don’t assume that every technical reference makes it a standard English word.

In engineering and mechanical contexts, the word fly can describe certain devices or components. For example, Merriam-Webster lists specialized meanings of fly related to machinery. These established meanings don’t automatically make flys the correct plural in every technical setting. Merriam-Webster’s definition of fly explains several of these uses.

Before using flys, check the relevant dictionary or technical source.

• Brand name: Follow the company’s official spelling.
• Proper noun: Preserve the established name.
• Technical document: Check the field’s terminology.
• Ordinary sentence: Use flies for the plural of fly.

For example, a technician should follow the exact terms used in an equipment manual. In general writing, though, flys is an uncommon and usually incorrect choice.

Why Do People Confuse Flys and Flies?

The confusion between flys and flies comes from familiar spelling patterns. Many English plurals simply add s to a singular noun.

For example, toy becomes toys, boy becomes boys, and day becomes days. These words make flys look like a reasonable option.

However, English spelling rules treat words ending in a consonant followed by y differently. The letter y usually changes to ies when forming the plural.

Compare these examples:

• Fly → Flies
• Baby → Babies
• City → Cities
• Party → Parties
• Toy → Toys

The same distinction affects verb forms. You write she flies, not she flys, because standard verb conjugation follows the same spelling pattern.

Conversation example:

“Why did my spell checker flag the word flys?”

“Because you probably meant flies. The spelling changes when a consonant comes before y.”

Learning this simple pattern can improve your grammar and communication skills. It also helps you avoid similar writing mistakes in professional emails and school assignments.

The Important Y-to-IES Rule

The Y-to-IES rule explains how many English words change when they become plural. When a noun ends in a consonant followed by y, you usually replace y with ies.

For example, fly becomes flies. The same pattern appears in words such as baby, lady, and country.

However, words ending in a vowel followed by y follow a different rule. You usually keep the y and add s.

Here’s the quick answer:

Spelling pattern	Rule	Examples
Consonant + y	Change y to ies	Fly → Flies
Vowel + y	Add s	Toy → Toys

These spelling rules cover many common plural forms. They also help explain why flies is the correct spelling in ordinary English.

Rule One: Consonant + Y

When a word ends with a consonant followed by y, change the y to ies to form its plural. This is the consonant + y rule.

The letter before y matters. In fly, the letter l is a consonant, so the plural becomes flies.

Here are more examples:

Singular	Plural
Baby	Babies
Lady	Ladies
City	Cities
Story	Stories
Party	Parties
Country	Countries
Family	Families
Library	Libraries
Army	Armies
Cherry	Cherries
Puppy	Puppies

This rule also helps with third-person singular verbs. For example, cry becomes cries, and try becomes tries.

Memory trick: Remember the baby rule. One baby becomes two babies, just as one fly becomes two flies.

This pattern isn’t an exception to English grammar. It’s a standard spelling rule that helps you form words correctly.

Rule Two: Vowel + Y

When a word ends with a vowel followed by y, keep the y and add s. This is the vowel + y rule.

For example, toy becomes toys, not toies. The vowel before y changes how you form the plural.

Look at these common examples:

Singular	Plural
Toy	Toys
Boy	Boys
Day	Days
Key	Keys
Monkey	Monkeys
Valley	Valleys
Ray	Rays
Holiday	Holidays

Notice that monkey follows this rule because the letter e comes before y. The same applies to valley and holiday.

This contrast explains the common spelling confusion between flys and flies. In fly, a consonant comes before y, so you change y to ies.

Keep this simple reminder in mind: consonant + y = ies; vowel + y = s.

Why “Flys” Looks Right but Isn’t

The word flys looks correct because many English words form their plurals by adding -s. For example, we write toys, boys, and days. However, the word fly follows a different spelling rule.

When a noun ends in a consonant followed by y, you usually change the y to ies to make it plural. That’s why the plural of fly is flies, not flys.

The same rule applies when you use fly as a verb with he, she, or it.

• Correct: The flies are near the window.
• Incorrect: The flys are near the window.
• Correct: The bird flies south every winter.
• Incorrect: The bird flys south every winter.

Conversation example:

• Alex: Is it flys or flies?
• Sam: Use flies. That’s the standard spelling.

Remember, “time flies” is correct, too. You should never write time flys in standard English.

Flys vs Flies: Side-by-Side Comparison

The difference between flys vs flies comes down to standard spelling and grammar. Flies is the correct form in everyday English when you mean more than one flying insect or describe someone or something flying.

Flys is generally a spelling mistake in ordinary writing. You might see it in a brand name or proper noun, but that doesn’t make it the standard spelling.

Feature	Flies	Flys
Standard spelling	Correct	Usually incorrect
Plural of the insect fly	Yes	No
Verb form with he, she, or it	Yes	No
Example	The flies are annoying.	The flys are annoying.
Everyday English	Common and correct	Avoid it
Special names	May appear	Possible as a proper name

Quick examples:

• Correct: Time flies when you’re having fun.
• Incorrect: Time flys when you’re having fun.
• Correct: The pilot flies every week.
• Incorrect: The pilot flys every week.

For school assignments, emails, blog posts, and professional writing, choose flies whenever the grammar calls for it. Standard dictionaries, including the Cambridge Dictionary, recognize flies as the plural of fly. See the dictionary definition.

Examples of “Flies” in Everyday Sentences

You’ll see flies used in two common ways. It can mean more than one flying insect, or it can describe an action performed by a person, animal, or object.

The sentence tells you which meaning applies. If flies refers to insects, it works as a noun. If it describes movement through the air, it works as a verb.

Here are simple examples you can use to understand the difference.

• The flies gathered around the fruit.
• A bird flies over our house every morning.
• Time flies when you’re having fun.
• The flag flies proudly above the building.
• Several flies entered through the open window.

As a Noun

When flies works as a noun, it means more than one fly. A fly is a small flying insect, such as a housefly.

The spelling changes from fly to flies because the word ends in a consonant followed by y. This follows the common consonant + y pluralization rule.

Examples:

• The flies are buzzing around the kitchen.
• We saw flies near the farm animals.
• A few flies landed on the picnic table.
• The farmer closed the barn to keep flies out.
• Those flies keep coming through the window.

Conversation example:

• Mia: Why are there flies in here?
• Leo: Someone left the window open.

A helpful tip is to check whether you can replace flies with insects. If the sentence still makes sense, flies is probably a noun.

As a Verb

Flies is also the third-person singular form of the verb fly. Use it with he, she, or it when describing an action in the present tense.

For example, you can say, “The eagle flies high.” You wouldn’t write, “The eagle flys high.”

The same spelling applies to people who travel by airplane and objects that move through the air.

Examples:

• My brother flies to Chicago every month.
• The eagle flies above the mountains.
• A kite flies well on windy days.
• The superhero flies across the city.
• Our school flag flies in the breeze.

Conversation example:

• Ava: How does your dad travel for work?
• Noah: He flies to different cities.

Remember the grammar pattern: I fly, you fly, we fly, and they fly. But he flies, she flies, and it flies.

Examples of “Flys” in Sentences

In standard English, flys is usually incorrect when you mean flying insects or describe something that flies. Use flies instead.

However, you might encounter Flys in a brand name, username, fictional name, or other proper noun. In those cases, the spelling may be intentional. Specialized technical contexts can also use unusual terms, so check the relevant source before changing them.

Here are examples of incorrect everyday usage and their corrections.

• Incorrect: The flys are all over the kitchen.
• Correct: The flies are all over the kitchen.
• Incorrect: My uncle flys to London.
• Correct: My uncle flies to London.
• Incorrect: Time flys when you’re having fun.
• Correct: Time flies when you’re having fun.

Conversation example:

• Ella: My spell checker marked flys as wrong.
• Max: That makes sense. In ordinary writing, you need flies.

If you see Flys in a company or product name, don’t automatically assume it’s a typo. Check the official spelling first. Otherwise, use flies to follow standard English grammar rules.

Common Mistakes Writers Make With Flys and Flies

Writers often confuse flys and flies because English has several different spelling patterns. Some words ending in y simply add s, while others change y to ies.

The key is to look at the letter before the y. If a consonant comes before it, the plural usually changes to ies. If a vowel comes before it, you generally add s.

Here are three common mistakes and how to correct them.

• Incorrect: The bird flys south.
• Correct: The bird flies south.
• Incorrect: There are many flys outside.
• Correct: There are many flies outside.
• Incorrect: She flys every weekend.
• Correct: She flies every weekend.

Spell-check tools can help catch these errors, but grammar knowledge matters, too. Learn the rule so you can spot mistakes in emails, school assignments, articles, and everyday messages.

Mistake One: Writing “The Bird Flys South”

This sentence contains a common verb spelling mistake. The correct version is The bird flies south because bird is a singular subject, and flies is the correct third-person singular form of fly.

In the simple present tense, most verbs add -s or -es with he, she, or it. When a verb ends in a consonant followed by y, you usually change the y to ies.

Correct examples:

• The bird flies south in winter.
• She flies to work twice a month.
• The airplane flies above the clouds.
• My favorite superhero flies through the sky.

Conversation example:

• Ben: Is it “the bird flys south”?
• Lily: No, write “the bird flies south.”

One easy way to remember this is to compare fly with try. You write he flies and she tries, not he flys or she trys.

Mistake Two: Writing “There Are Many Flys”

This mistake happens when writers try to form the plural of fly by adding only -s. However, the correct plural noun is flies.

The rule is simple: when a noun ends in a consonant plus y, change the y to ies. This pattern also appears in words such as baby/babies, city/cities, and party/parties.

Correct examples:

• There are many flies in the garden.
• The flies gathered around the food.
• We noticed several flies near the barn.
• Those flies keep landing on the window.

Conversation example:

• Sara: Are there many flys outside?
• Omar: The correct spelling is flies.

Don’t confuse this pattern with words such as toys and boys. Those words have a vowel before the y, so you simply add s. The letter before y determines the spelling pattern.

Mistake Three: Applying the Wrong Grammar Rule

Not every word ending in y changes to ies. Applying one spelling rule to every word can create unnecessary mistakes.

You need to check whether the letter before y is a consonant or a vowel. This small detail helps you choose the correct plural form and verb spelling.

Consonant + y: change y to ies

• Baby → Babies
• City → Cities
• Fly → Flies
• Try → Tries

Vowel + y: add s

• Toy → Toys
• Boy → Boys
• Day → Days
• Key → Keys

Conversation example:

• Jack: If fly becomes flies, does toy become toies?
• Emma: No. You keep the y in toys because a vowel comes before it.

Use this quick memory trick: consonant + y becomes ies; vowel + y gets s. It helps you avoid common spelling mistakes in everyday writing.

Why Spell Checkers Flag “Flys”

Spell checkers often flag flys because it usually isn’t the correct spelling in standard English. When you mean more than one flying insect, the correct word is flies. The same spelling applies when you use fly with he, she, or it in the present tense.

Tools such as Microsoft Word, Google Docs, and Grammarly can help you catch this mistake. However, spell checkers don’t always understand context, especially when you use brand names or unusual technical terms.

Examples:

• Incorrect: The flys are near the door.
• Correct: The flies are near the door.
• Incorrect: She flys to work.
• Correct: She flies to work.

Conversation example:

• Mia: Why is my document underlining flys?
• Noah: It’s probably flagging a spelling mistake. Try flies instead.

Remember, spell checkers are useful, but learning the grammar rule helps you catch errors on your own.

Case Study: A Simple Email Mistake

Imagine you’re writing a quick email to a coworker about insects in the office. You type, “There are too many flys near the kitchen.” The message is easy to understand, but the spelling is incorrect.

A spell checker may underline flys and suggest flies. Once you make the correction, your email looks more professional and follows standard English grammar.

Original email:

Hi Sam,

There are too many flys near the kitchen window. Could you please close it?

Thanks!

Corrected email:

Hi Sam,

There are too many flies near the kitchen window. Could you please close it?

Thanks!

The correction is small, but it improves the quality of your writing.

Conversation example:

• Sam: I noticed a spelling error in your email.
• Alex: Thanks! I should have written flies.

The same rule applies to work reports, school assignments, blog posts, and business emails. A quick review can help you avoid common spelling mistakes.

How Dictionaries Define Flies

Major English dictionaries recognize flies as the standard plural of the noun fly. They also list flies as the third-person singular form of the verb fly.

The meaning depends on how you use the word in a sentence. As a noun, flies refers to multiple flying insects. As a verb, it describes someone or something moving through the air or traveling by aircraft.

For example, “The flies are buzzing” uses flies as a noun. In “The eagle flies high,” it functions as a verb.

You can check these definitions in reliable dictionary sources:

• Cambridge Dictionary: Definition of flies.
• Merriam-Webster: Definition of fly.
• Oxford Learner’s Dictionaries: Definition of flies.

Example: The flies disappeared when we closed the window.

These references support the standard spelling. If you’re unsure, checking a dictionary is a reliable way to confirm your choice.

How Dictionaries Define Flys

Most standard English dictionaries do not list flys as the normal plural of fly or its standard third-person singular verb form. For these meanings, the correct spelling is flies. Dictionary.com’s entry for fly confirms both forms.

Dictionary

However, that doesn’t mean the letter sequence flys can never appear in English. It may occur in a proper name, brand, or unusual historical or specialized context.

When you see flys in a sentence, check what the writer means before correcting it.

• Everyday noun: The flies are outside.
• Everyday verb: She flies to work.
• Proper name: Keep the official spelling if a business uses Flys.
• Unfamiliar technical term: Check a reliable specialist source.

Conversation example:

• Liam: I found the word Flys in a company name. Is it wrong?
• Emma: Not necessarily. Proper names can use unusual spellings.

For normal writing, use flies for the insect plural and the verb form. This keeps your spelling clear and consistent.

The History Behind the Word “Flies”

The word fly has a long history in English. It comes from Old English flēogan, meaning to fly or move through the air. The noun fly, referring to the insect, also has Old English roots. Over time, English spelling and grammar developed recognizable patterns for forming plurals and verb forms.

Collins English Dictionary

The spelling flies follows a pattern used by many English words that end in a consonant plus y. Instead of adding only s, English usually changes the y to ies.

You can see this pattern in familiar words:

• Baby → Babies
• City → Cities
• Story → Stories
• Fly → Flies

These spelling patterns help readers recognize words and understand their grammatical roles.

Conversation example:

• Noah: Why doesn’t fly become flys?
• Ava: English changes the consonant-plus-y ending to ies.

You don’t need to memorize the word’s entire history. Learning the spelling rule is enough for most everyday writing.

Flys vs Flies in American and British English

The spelling difference between flys and flies does not change between American and British English. In both varieties, flies is the standard plural of the insect fly and the third-person singular form of the verb fly.

You can use the same spelling in schoolwork, emails, articles, and everyday messages on either side of the Atlantic.

Example	American English	British English
Plural noun	The flies are outside.	The flies are outside.
Verb	She flies to Boston.	She flies to London.
Idiom	Time flies.	Time flies.

Some words do have different American and British spellings, such as color/colour and organize/organise. However, flies is not one of those spelling differences.

Conversation example:

• Chris: Should I write flys in British English?
• Taylor: No. Use flies in both varieties.

If you’re learning English, focus on the consonant-plus-y rule rather than memorizing separate regional spellings. It works the same way in American and British English.

The Grammar Rule You Should Memorize

To choose between flys and flies, remember one basic spelling rule: when a word ends in a consonant followed by y, change the y to ies in the plural or the relevant third-person singular verb form.

The word fly ends in l plus y. Since l is a consonant, the correct form is flies.

Examples:

• Fly → Flies
• Baby → Babies
• City → Cities
• Story → Stories
• Try → Tries
• Cry → Cries

However, when a vowel comes before y, you usually keep the y and add s.

• Toy → Toys
• Boy → Boys
• Day → Days
• Enjoy → Enjoys

Conversation example:

• Mia: Why do we write flies but toys?
• Noah: The letter before y is different.

This grammar rule helps you avoid common spelling mistakes in writing. It also makes the difference between flys and flies much easier to remember.

Memory Trick: The Baby Rule

A simple way to remember flies vs flys is to use the baby rule. When a word ends in a consonant plus y, change the y to ies to form its plural.

Think about the word baby. You write babies, not babys. The same pattern applies to fly, which becomes flies.

Use this quick memory trick:

• Baby → Babies
• Lady → Ladies
• Puppy → Puppies
• Fly → Flies
• City → Cities

But remember that this rule depends on the letter before y. If a vowel comes before y, you usually add s instead.

• Toy → Toys
• Key → Keys
• Boy → Boys

Conversation example:

• Ella: How can I remember the spelling of flies?
• Max: Think of baby becoming babies. The same rule applies.

Whenever you wonder whether to write time flies or flys, remember the baby rule. The correct phrase is time flies because fly follows the consonant-plus-y pattern.

Words That Follow the Same Pattern

Many English words follow the same spelling pattern as fly. When a word ends in a consonant followed by y, you generally replace y with ies to form its plural. Some verbs follow the same pattern in the third-person singular present tense.

Learning these examples can make the rule easier to apply. You’ll also recognize the pattern more quickly when writing essays, emails, captions, or reports.

Singular or base form	Correct form
Baby	Babies
Lady	Ladies
City	Cities
Story	Stories
Party	Parties
Country	Countries
Family	Families
Library	Libraries
Army	Armies
Cherry	Cherries
Puppy	Puppies
Try	Tries
Cry	Cries
Fly	Flies

Conversation example:

• Ben: Is citys correct?
• Ava: No, it’s cities, just like flies.

These words reinforce the same spelling rule. Practicing a few examples each day can help you avoid common errors.

Words That Follow a Different Pattern

Not every word ending in y changes to ies. When a vowel comes before the y, you usually keep the y and add s to form a plural. Verbs follow a similar pattern in the third-person singular present tense.

This is why toy becomes toys, not toies. The letter before y determines which spelling rule applies.

Examples:

Singular or base form	Correct form
Toy	Toys
Boy	Boys
Day	Days
Key	Keys
Monkey	Monkeys
Valley	Valleys
Ray	Rays
Holiday	Holidays
Enjoy	Enjoys
Play	Plays

Conversation example:

• Liam: If fly becomes flies, should day become daies?
• Mia: No. A vowel comes before the y in day, so you add s.

Remember the difference: consonant + y usually becomes ies, while vowel + y usually takes s. This rule helps you spell flies correctly without guessing.

Common Phrases That Use “Flies”

The word flies appears in everyday expressions and idioms. These phrases often use the idea of flying insects to describe time, observation, or events happening in large numbers.

Some expressions use flies as a plural noun. Others use flies as a verb, such as time flies. Learning these phrases helps you understand how the word works beyond basic grammar.

Common expressions include:

• Time flies: Time passes quickly.
• A fly on the wall: An unnoticed observer.
• Drop like flies: Fall, become ill, or leave in large numbers.
• There are no flies on someone: That person is alert or clever.

Conversation example:

• Sara: How is it already the end of the year?
• Omar: Time flies when you’re having fun!

These expressions can make your English sound more natural. Just remember that idioms often have meanings beyond their literal words.

Time Flies

Time flies is a common English idiom that means time passes surprisingly quickly. People often use it when an enjoyable activity ends sooner than expected or when they realize how much time has passed.

English meaning – Cambridge Dictionary

For example, you might start watching a movie with friends and suddenly notice that it’s midnight. You could say, “Time flies when you’re having fun.”

Examples:

• Time flies when you’re with good friends.
• I can’t believe we graduated already. Time flies!
• The weekend went by so quickly. Time flies.

Conversation example:

• Amy: We’ve been talking for three hours!
• Jack: Really? Time flies when we catch up.

The correct spelling is always time flies, not time flys, in standard English. Here, flies is the third-person singular verb form because time is singular.

Flies on the Wall

The expression people usually mean is a fly on the wall, not flies on the wall. It describes someone who observes a situation without being noticed. The phrase often appears when someone wants to know what happens during a private conversation or event.

Cambridge English Dictionary

For example, you might wonder what your friends say about a surprise party when you aren’t there. You could say, “I’d love to be a fly on the wall.”

Examples:

• I’d love to be a fly on the wall during their meeting.
• She wished she could be a fly on the wall.
• He wanted to be a fly on the wall during the interview.

Conversation example:

• Mia: I wonder what they discussed after I left.
• Noah: You wish you could be a fly on the wall!

This idiom uses fly in the singular because it imagines one unnoticed observer. The phrase is figurative, so nobody expects a real insect to listen in.

Like Flies

The words like flies commonly appear in the idiom drop like flies. This expression describes people or things falling, becoming ill, dying, or leaving in large numbers. The exact meaning depends on the context.

Cambridge English Dictionary

For example, if many people leave a class because it’s too difficult, you might say they’re “dropping like flies.” The phrase can sound dramatic, so use it carefully when discussing serious situations.

Examples:

• People were dropping like flies in the extreme heat.
• Team members dropped like flies after the long race.
• Customers left the event like flies leaving a room. (A creative comparison, not the standard idiom.)

Conversation example:

• Ben: Why is everyone leaving the class?
• Ella: They’re dropping like flies because the exam is difficult.

In this idiom, flies is plural. The phrase doesn’t mean that people literally turn into insects. It simply emphasizes that many people are falling or leaving quickly.
