Solution(By Examveda Team)

Notoptera, Ice crawlers and Rock crawlers are also known as Grylloblattodea.
Grylloblattidae, commonly known as the icebugs, or ice crawlers, is a family of extremophile and wingless insects that live in the cold on top of mountains and the edges of glaciers.
They belong, along with Mantophasmatidae (rock crawlers), to the order Notoptera.
These are wingless insects mostly less than 3 cm long, with a head resembling that of a cockroach, with long antennae and elongated cerci arising from the tip of their abdomen. They cannot tolerate warmth (most species will die at 10°C) and many species have small distribution ranges.
