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.
American Needlefly
A delicate needle-thin stonefly of Appalachian headwater streams. Nymphs are important processors of autumn-shed leaf litter.
Did You Know?
Multiple Leuctra species can coexist in the same stream by emerging at different times of year.
