Snow Fleas Are Real And Can Be Found In Iowa

Snow has been a hot topic this month, and here's a fun fact you might not be aware of: "snow fleas" are a real phenomenon. If you're in a snowy region, you might encounter them. The good news is, they're not nearly as bothersome as regular fleas.

Although snow fleas aren't actually fleas, they closely resemble them. During warmer spells in winter, when the snow begins to melt, these tiny creatures can be seen scattered across the snow like tiny specks. Snow fleas also share the remarkable jumping ability that regular fleas are famous for, making them surprisingly nimble despite their small size.

Fortunately, snow fleas are far less bothersome than their flea cousins. They don’t bite or harm humans or pets, making them more of an interesting winter oddity than a real threat.

These Are Snow Fleas In Iowa

According to the Farmers Almanac, and other sources... "snow fleas" are not actually fleas. They also thrive in the winter.

Snow fleas are not actually fleas — and officially, they aren’t classified as insects, either, though they do look like bugs. These small wingless creatures are often referred to as “springtails,” but their scientific name is Hypogastrura harveyi or Hypogastrura nivicola, depending on the species. Snow fleas are classified as hexapods, which is a subtype of the arthropod family. Like insects, snow fleas have six legs but researchers say that they are more closely related to crustaceans.

Thankfully, snow fleas do not bite, and they have a fascinating way of surviving the cold. They are equipped with a special antifreeze-like substance in their bodies, allowing them to thrive even in freezing temperatures. This special adaptation allows them to remain active throughout the winter, hopping around the snow with ease. It's yet another example of how nature has come up with incredible ways for creatures to thrive in even the harshest environments.

Snow fleas produce their own type of antifreeze, a protein that is rich in the amino acid glycine. Glycine prevents the formation and enlargement of ice crystals, enabling these creatures to keep on munching organic materials despite the bitter cold.

Still, it's a good idea to keep an eye out for snow fleas when you're near trees or areas with melting snow.
