It's winter, and no discussion of winter wildlife is complete without mention of the humble snow flea. Generally seen as tiny moving specks on snow in late winter/early spring. They are actually springtails and can jump so suddenly as to seem to disappear. Since they don't bite or invade your food supply, they have curiosity value only to hikers. So, who has seen them, and when did you first realize that there really are bugs out there in winter? (Maybe this is a pretty lame thread, but we haven't had any excitment on the wildlife forum in awhile.)
