Grylloblattodea is a small order of extremophile and wingless insects that live in the cold on top of mountains, consisting of a single family, Grylloblattidae. 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. Their closest living relatives are the phasmids and the recently-discovered order Mantophasmatodea (Cameron et al., 2006).
This order includes a single family with 5 genera and 25 species.
ITIS Number 102429
