Billions of nocturnal Bogong moths migrate up to 1,000 km to cool caves in the Australian Alps that they have never previously visited. New research shows how they may find their way there and back.

Those insects you see flying in crazed circles are trying to keep their backs towards the light because they think that direction is up, new research suggests.

When you see a dead butterfly, put it an envelope, stamp it and stick it in the mail. Scientists want to see if certain contaminants are present in butterflies, and may be why so many of the insects are in steep population decline.

Butterflies likely split from nocturnal moths around 100 million years ago in present-day western North America or Central America, a new study of the winged insects finds.
