Found: In streams and rivers with rocky bottoms and logs to hide under.

Crayfish on rocks

This water beetle is usually found swimming on the surface of a lake or pond where they swim wildly in circles. This movement makes small waves, which may help them find insects to eat via echolocation.

WILDLIFE SCAT

Many animals, such as squirrels, raccoons, owls, bats, weasels, porcupines, songbirds, and others, make their homes inside tree holes. The holes can occur from tree decay or broken branches, or else with the help of woodpeckers. While it's rare to see the occupant, let's assume it's a home for someone.

Squirrels love to eat pinecone seeds. You may come across a pinecone cob and scales in a pile called middens that the squirrel left behind. Some middens get a few feet deep under a squirrel's favorite lunch spot.

SQUIRREL MIDDENS

Banner reads: Amphibians and reptiles

Snapping turtles are Minnesota’s largest turtle species and weigh up to 45 pounds. They're graceful swimmers who spend most of their time in the water, swimming along the surface. Once overharvested and on the endangered species list from 1984-2013, they have now rebounded. They are docile and avoid humans but will defend themselves if threatened.
