Winter is usually seen as a cold and dreary season, but these amazing critters bring an interesting twist to the frosty environment. Snow bugs and ice worms are two cool critters that are hard to spot but are nevertheless important members of the arctic ecosystem. Learn more about these incredible creatures and their fascinating abilities.

About Snow Bugs

Snow bugs, also known as snow fleas, are tiny wingless insects found on mountain tops, in tundra and even in plowed fields during the winter. These creatures stay hidden under the snow during most of the day to keep from freezing and become active in the morning and late afternoon.

Appearance

Snow bugs are about 1/4 inch long, black or reddish-brown in color and have 12 short legs. They are covered with small hairs that give their bodies a bristly surface.

Feeding Habits

Snow bugs search for food during the winter, mostly in the form of bacteria, decaying plant material, plant nectar and fungi. They are important parts of the food chain and provide a source of food for birds and predatory insects.

Reproduction

Snow bugs are capable of laying eggs during the winter months and then stockpiling them in the snow, where they can develop over the cold months. When the snow starts to melt, adults emerge and the new eggs will hatch.

About Ice Worms

Ice worms reside in ice and snow in Arctic and Antarctic regions, and are rarely seen by humans. Despite the harsh environment, these cold-adapted worms have a life cycle that is perfectly suited for their environment.

Appearance

Ice worms are microscopic, usually only measuring about 0.04 to 0.06 inches long. They look like round, segmented worms.

Hibernation

Ice worms curl up during the winter months to hibernate and become dormant. In the spring they will uncoil and thaw out when the temperatures rise. This adaptation helps them survive the harsh winter.

Food Sources

Ice worms are scavengers and consume bacteria, algae, and other small organisms in order to survive.

Reproduction

Ice worms reproduce during the summer. They lay eggs in snow banks, which arein turn are buried in the winter. Eggs can remain dormant for up to seven years and then will hatch when the temperature rises.
