Rock Crawler
A pale wingless insect living on high-altitude ice and snowfields. It is active only at near-freezing temperatures.
Did You Know?
Restricted to tiny patches of permanently cold habitat and acutely threatened by climate change warming its mountain homes.
Northern Rock Crawler
A rare ice-dwelling insect that lives on glaciers and snowfields at near-freezing temperatures. Handling one with bare hands can overheat and kill it.
Did You Know?
Rock crawlers are so cold-adapted that a human hand is hot enough to kill them — they prefer temperatures between 1-4C and die above 20C.
