You need to learn how to use Google search. Enter the keyword Maculinea and you'll get a list of links about a species that spends its caterpillar stage as a parasite in ant nests.

I'm doing a biology project and I need to pick one species from order Lepidoptera

and talk about the body plan, life cycle, habitat, and the niche of that species but when I look up specific species online I don't get much of that info, also the library wasn't that helpful :\ does anyone know a website or know about them??
