Random Insect Generator

Generate a random insect, from beetles and butterflies to bees and ants, for a nature project, a writing prompt, or pure curiosity.

About this generator

This generator draws from a curated list of 244 real insect species across twelve orders and groupings -- beetles, butterflies and moths, bees wasps and ants, flies, true bugs, grasshoppers and crickets, dragonflies, cockroaches and termites, mantises, stick and leaf insects, aquatic insects, and parasitic insects like fleas and lice.

Every result here is drawn using crypto.getRandomValues() -- the Web Crypto API's cryptographically secure randomness -- instead of Math.random(), so it's genuinely unpredictable, not just statistically random. Learn more.

What people use it for

Students and teachers use it for a biology worksheet or a quick entomology trivia round. Writers and game designers use it to pick a real basis for a creature or setting detail. It also works for a nature-journaling prompt, a "guess the bug" icebreaker, or just satisfying curiosity about how many kinds of insects actually exist beyond the handful most people can name.

How it works

Generate draws one species at random from the full 244-entry pool using the site's cryptographically secure randomness, guaranteed not to repeat whatever result is currently showing in single-result mode. Filtering by order narrows the pool to just that group before drawing, and multi-result draws avoid duplicates until the (filtered) pool is exhausted.

Common questions

Are these real insects?

Yes -- all 244 are real, existing species across real taxonomic orders, not invented.

Can I filter by type of insect, like only beetles or only butterflies?

Yes -- use the filter button to pick one or more of the twelve orders and groupings. Generate will then only draw from species in the groups you've selected.

Will it show me the same insect twice in a row?

Not in single-result mode -- each new roll is guaranteed to differ from the one currently on screen.

Does this include spiders or other bugs that aren't technically insects?

No -- this list sticks to true insects (six legs, three body segments). Spiders and other arachnids aren't included.
