Bees, Butterflies and Beyond: 34 Insects in English to Add to Your Collection

Caterpillar, cockroach, cricket, oh my!

Did you know that there are over 900 thousand different kinds of insects, which makes up 80% of the world’s animal species?

Don’t worry, though; you don’t have to learn all 900 thousand to be insect fluent in English—unless, of course, you want to!

In this post, we will be focusing on 34 common insects in English to add to your practical (useful) vocabulary. These are the bugs (another word for insects) that you will likely see while walking around or playing in your backyard and, hopefully not, but maybe in your house too.

Why Learn the Names of Insects in English?

Expand your English vocabulary

Learning insect names is a great way to expand your English vocabulary. As you learn a new insect name, consider writing it down. Maybe you can even try drawing a picture of it next to the word or include some adjectives (words that describe nouns) to describe the insect. Writing down new vocabulary is also a great way to get some spelling practice in.

Launch a career in science or environmental studies

If you are applying for an English-speaking position in the science field, your employer will expect you to have an understanding of advanced scientific terms. But you have to start somewhere, right? Learning the names of insects in English is an excellent place to begin!

Have a more meaningful visit at zoos and natural spaces

If you are exploring a zoo, park, natural history museum or even a greenhouse (an enclosed place where plants are grown) in an English-speaking environment, it would be helpful to understand the names of insects in English. You might see signs explaining the types of insects found in a space, so understanding this vocabulary will help you get more out of this type of experience.

Understand pop-culture references

From sports teams to superheroes (Spiderman, Antman, etc.), insects are frequently used in pop culture. By learning these bug names, you will pick up on references in movies or television shows that you might have otherwise missed.

For example, you can hear insect names used in the videos below. And if you enjoy learning new vocabulary with videos and fun clips, then you’ll want to check out the many native English videos on FluentU.
