Glossosoma intermedium

Range & Status

Rare; the only recent records are from two small streams in the English Lake District.

Regional Distribution

There is a single record for Cornwall (in 1971). This is almost certainly a misidentification of one of the other two common Glossosoma species as the key then available to larvae led to many such errors occurring.

Habitat & Ecology

Occurs in streams, in fine silt, sand, gravel and small pebble substratum.


Not known.


Special recognition for host watercourses.
