... snow fleas, that is. Monday it was so warm (40oF) that I decided to check out the old oak log behind my garden. It’s covered with moss and lichens, and on Monday the snow below it was covered with snow fleas!
Seen from a couple feet away, snow fleas look like specks of pepper.
Up close, they look like bigger specks of pepper! Unless you have a hand lens, and then you can see their legs. They have six, but they aren’t insects. And they aren’t even fleas. They’re teensy arthropods called Collembola, or springtails. They’re a whopping 1/8 inch long and have two tail-like structures that are tucked under their belly – until they release and catapult the snow flea into the air, flinging them up to 100 body lengths away. It’s a great ride with one problem – the snow fleas have no control over where they land.
Turns out snow fleas have been around a long time, at least 400 million years. By comparison, the first dinosaur didn’t show up until 240 million years ago, writes Judy Rosovsky. Check out her article at VT Agency of Agriculture, Food & Markets.
Snow fleas have been found on Mt. Everest, so finding them in my backyard isn’t unusual. They’ve got a protein that acts as an anti-freeze to keep their cells from freezing, says Judy. And they don’t bite people – or pets. Instead, these tiny-but-mighty jumpers subsist on eat leaf litter, decaying plants, and fungi.
This week, if you’ve got snow and a warm day, go on a snow flea hunt!
