Like most common names, "Spotted Sedge" can refer to more than one taxon. They're previewed below, along with 2 specimens. For more detail click through to the scientific names.

Caddisfly Genus Hydropsyche

These are often called Spotted Sedges.

Though still extremely important, the impact of this genus is somewhat less because entomologists recently reclassified 10 of the 15 most important Hydropsyche species listed by Gary LaFontaine in Caddisflies into the genus Ceratopsyche.

See the Hydropsychidae family page for details shared by these genera.

Caddisfly Genus Ceratopsyche

These are sometimes called Spotted Sedges.

This may be the most important genus of caddisflies on American trout streams. Hydropsyche once held that honor, but its best species have been reclassified into Ceratopsyche.

See the Hydropsychidae family page for details shared by these genera.
