Grylloblattodea is a small order of extremophile insects that live in the cold on top of mountains. They are commonly called grylloblattids, but are also sometimes called rock crawlers or icebugs. Their appearance evidently puzzled the scientist who discovered them; the first species named was Grylloblatta campodeiformis, which means "It looks like a cricket, a cockroach, and a Campodea" (a kind of two-pronged bristletail). Most are nocturnal and appear to feed on detritus. They have long antennae (23-45 segments) and long cerci (5-8 segments), but no wings.
This order includes a single family with 2 genera and 6 species.
