About Stoneflies: the wider group

Order-level background for Plecoptera, the group containing Isogenoides hansoni. Species-specific details appear above.

Group overview

Plecoptera (stoneflies) includes ~3,700 described species. Stonefly nymphs are among the most pollution-sensitive aquatic insects - they require cold, clean, well-oxygenated running water to survive.

Ecological role of the group

Stonefly nymphs are important shredders of leaf litter in streams, breaking down organic material and making nutrients available to other organisms. Adults are a key food source for trout and are widely imitated in fly fishing.

Economic and practical significance of the group

Stoneflies are considered the gold standard bioindicator for water quality monitoring worldwide. Their absence from a stream is one of the strongest signals of pollution or environmental degradation.

Recorded sources for this group: EPA, freshwater ecology research, fly fishing industry. Imported estimates may describe particular regions or reporting periods.
