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.
White-shouldered House Moth
A small greyish moth with a conspicuous white head and thorax that is common in buildings year-round. It is found worldwide as a minor household pest.
Did You Know?
It is one of the few moths that can breed continuously indoors throughout the year without a dormant phase.
