New Zealand Stonefly
An endemic New Zealand stonefly found in clean, fast-flowing streams. The aquatic nymphs are important indicators of water quality. Adults are poor fliers and often found resting on streamside vegetation. Stonefly diversity in New Zealand is remarkably high.
Did You Know?
New Zealand stoneflies are such sensitive indicators of water quality that their absence from a stream is a reliable sign of pollution or degradation.
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.
