Grylloblattodea, also called ice crawlers, had ancient relatives that thrived during colder periods millions of years ago.
These ancestors were tough insects adapted to harsh, icy environments.
Highlights:
- Slow-moving, nocturnal insects
- Fed on dead organic material
- Disappeared as climate warmed after the last Ice Age
Today, only a few species survive, but their extinct ancestors give us clues about insect adaptation to extreme climates.
