Species profile: Cheumatopsyche lepida

October 16, 2015

Cheumatopsyche lepida (Pictet, 1834)

Cheumatopsyche lepida is one of nine members of the Family Hydropsychidae found in Ireland, and the sole representative of the genus in Britain and Ireland. It is a species whose larvae can be found in the lower reaches of large rivers.

Cheumatopsyche lepida has a univoltine reproductive cycle (one generation per year) and lives up to one year. Its feeding ecology is predominantly passive filter feeding, with some predation and grazing/scraping.

Characteristic features of the larva of Cheumatopsyche lepida include the presence of large, rectangular dorsal plates on all three thoracic segments, tufted gills on the abdominal segments and the numerous long bristles present on the front margin of the pronotum.

Adults of Cheumatopsyche lepida can be found on the wing from June to September.

Records of Cheumatopsyche lepida on the National Biodiversity Data Centre website can be found here.
