This common name refers to only one genus. Click its scientific name to learn more.
Caddisfly Genus Cheumatopsyche
These are sometimes called Little Olive Sedges.
To generalize broadly, Cheumatopsyche is found lower in the watershed than the similar genera Hydropsyche and Ceratopsyche. It is also smaller, but there is wide variation in size and color between the species. See the family Hydropsychidae page for life cycle details common to these genera.
The most important trout stream species are Cheumatopsyche campyla and Cheumatopsyche pettiti.

I photographed this one recently dead. It's hard to keep caddis pupae alive for very long in a collection container.
