Warble Fly
A large, hairy bee-like fly whose larvae migrate through the bodies of cattle for months before emerging from cysts in the back. Adults have vestigial mouthparts and cannot feed.
Did You Know?
The buzzing of a single warble fly approaching can cause an entire herd of cattle to stampede in panic, a behavior called gadding.
Large Spring Stonefly
One of the largest European stoneflies with a distinctively broad, flattened head. Nymphs are apex invertebrate predators in upland streams.
Did You Know?
Despite their large wings, adults are poor fliers and prefer to run along streamside rocks.
