Appalachian Springfly
A rare springfly restricted to a few clean Appalachian headwater streams. Nymphs are predatory on small invertebrates among gravel substrates.
Did You Know?
Its extremely limited range makes it one of the rarest stonefly species in North America.
Brassy Willow Beetle
A small, shiny metallic bronze to greenish beetle that feeds on willow and poplar. Adults overwinter in leaf litter and emerge in spring to colonize new willow growth.

Larvae secrete salicylaldehyde, a chemical obtained from salicin in willow leaves, which smells like antiseptic and deters predators.
