Mountain Long-legged Fly
A metallic green fly with long legs found in damp alpine meadows. Males perform elaborate courtship displays using their ornamental leg scales.
Did You Know?
Males wave their decorated legs like flags during courtship to impress females.
Saddle-Case Caddisfly
A small caddisfly whose larvae build distinctive saddle-shaped cases from tiny stones. When it pupates, it cuts the case free from the rock and seals itself inside.
Did You Know?
Saddle-case caddisfly larvae graze algae so efficiently that they can create visible clean patches on otherwise algae-covered stream rocks.
