Urban Observation of the Week: Caddisflies Under Ice

During the winter, snow covers the ground and lakes freeze. The trees have lost their leaves, the birds flew south, and the bears hibernate. But where do the bugs go? Some also go south for the winter, like the Monarch Butterfly. But others actually stay in the north and are aquatic, living under the ice. In fact, there are a handful of researchers, like Rose Martin, that specifically check in on them for their research! Here are some caddisflies and bonus zooplankton under the ice!

Do you have a photo or video of an urban species doing something unusual? What about a rare plant or animal that you were surprised to find in a city? If so, let Lindsay know or Tweet at us and you could be featured as a future observation of the week!
