Grylloblattidae is a family of extremophile and wingless insects that live in the cold on top of mountains. It belongs, as Mantophasmatidae, to the order of Notoptera[2].
They are commonly called grylloblattids, but are also sometimes called ice crawlers or icebugs. Their appearance evidently puzzled the scientists who discovered them, E.M. Walker and T.B. Kurata; the first species named was Grylloblatta campodeiformis, which means "cricket-cockroach shaped like 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 recently-discovered Mantophasmatodea.[3]
The family is placed in its own suborder, Grylloblattodea, and in its own former[2] order, Grylloblattaria. It contains 5 genera and 25 species.[4]
