Bohemia Ecological Preserve

The bumpy brown object is a Caddis Fly larvae that has built a protective case of silk decorated with gravel, sand, twigs or other debris. The winged adult females dive to lay their eggs on the creek bottom. When they're done, instead of swimming back to the surface quickly, they dead-drift and float up to the surface. This makes them exceptionally vulnerable to trout. The beige and red clumps are eggs of some other creatures.
