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.
Arctic Caddisfly
A small, hairy-winged caddisfly with dark brown wings held tent-like over the body. Larvae build portable cases from sand grains and small stones. It is one of the most northerly distributed caddisflies in the world.
Did You Know?
Some Arctic populations of this caddisfly reproduce by parthenogenesis, with females producing offspring without mating.
