Trichopteran species list
DISTRIBUTION AND ECOLOGY
Plectrocnemia geniculata is found in central and southern Europe and North of Africa. In
the Iberian Peninsula is widely distributed but it lacks in northwestern region.
This species has been recorded in a wide range of altitudes (Décamps, 1967). In the Foix
basin it has been found in headwaters with a very good ecological status.
