Chinese Rock Crawler

A rare ice crawler found in mountainous regions of China. It is wingless and nocturnal, emerging only in cold conditions to forage on the surface.

💡

Did You Know?

Rock crawlers can take five to seven years to reach maturity due to the cold temperatures slowing their metabolism.

Strong Casemaker Caddisfly

A caddisfly that builds smooth, slightly curved sand-grain cases up to 20 mm long. Larvae inhabit cool, clean streams with gravel and cobble substrates.

💡

Did You Know?

The cases are so precisely constructed they were once thought to be the work of marine worms rather than insects.
