+1. There's even "beetle" [0.a], "cockroach" [0.b] and "fly" [0.c] emoji in the Unicode, that are way closer to what I envision as a "software bug" than caterpillars, centipedes (!)[2.c] and even slugs (!!)[1.a] that are used to represent the "bug" you've linked [1].

And yes, technically it should be a moth [2], probably (?).

I usually check http://scrumoji.org for some inspiration, there the caterpillar is used for bug so might be the source for some others too!

At a previous job we used https://gitmoji.dev, which scrumoji is based on. At some point I started using the ladybug emoji for bugs because it's actually a bug while my colleagues kept using the caterpillar emoji because they preferred caterpillars. I thought it was a nice way to bring some individuality into our commit messages!

"An inordinate fondness for beetles."

A possibly apocryphal reply to theologians who inquired if there was anything that could be concluded about the Creator from the study of creation; as described in "Homage to Santa Rosalia, or why are there so many kinds of animals" by G. Evelyn Hutchinson in American Naturalist (May-June 1959); This alludes to the fact that there are more types of beetles than any other form of insect, and more insects than any other kind of animal.

the bug is probably a caterpillar, because it is way cuter and easier to distinguish. ...or they might have just looked at https://gitmoji.dev/
