Insects Vocabulary in English: 115+ Bug Words You Will Actually Use
Names, body parts, life stages, and bug-behavior words—each with a quick meaning and an example sentence.
If you can say mosquito and cockroach, you are already surviving. This list helps you go from “Ew, a bug” to “Oh, that is a dragonfly (and it is harmless).”
Heads-up: everyday English often calls lots of tiny crawly things “bugs,” even if they are not technically insects. We keep it practical, but we also keep it honest.

Calling everything a “bug” is like calling every animal a “dog.” Convenient? Yes. Accurate? Absolutely not. But hey—language is messy. Like a picnic.
