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.

Mount Halla Ice Crawler

A Korean ice crawler restricted to the high elevations of Mount Halla on Jeju Island. It is nocturnal and emerges only during freezing conditions.

💡

Did You Know?

Climate warming directly threatens this species as its cold mountain habitat shrinks upward with no higher ground to retreat to.
