In a new study, Northwestern University scientists explored how snow flies—small, wingless insects that crawl across snow to find mates and lay eggs—survive in freezing cold temperatures. They ...

Insects show a remarkable ability to adapt to a huge range of temperatures. This is even more impressive when you remember that they are cold-blooded and therefore at the mercy of external ...

The winter is usually when insects die or go into a state of paused development, but for tiny specks on the white snow called snow flies, it's time to run around, find a lover and make baby snow flies ...

Unlike most bugs, snow flies thrive in the cold—thanks to a baffling mix of genetic kinks that scientists never expected to find. Reading time 3 minutes Insects are cold-blooded. Low temperatures make ...

A few years ago, John Tuthill was trail running in the Cascade mountains in Washington state when he spotted something dark skittering across the snow. It was about the size of a wild blueberry, with ...

Learn how snow flies use antifreeze proteins and generate heat to stay active in freezing temperatures. When the snow hits, most insects disappear. Snow flies come out. They crawl across the surface ...

In October 2016, while hiking through a treacherous mountain pass, John Tuthill saw something move. He was almost 8,000 feet above sea level in Washington’s Alpine Lakes Wilderness, braving high winds ...

Snow flies might be undergoing an identity crisis. In a new study, Northwestern University scientists explored how snow flies — small, wingless insects that crawl across snow to find mates and lay ...

Snow flies are able to survive and remain active in subzero temperatures, which is unusual for insects. New genomic studies have revealed that they use a combination of strategies, including a protein ...
