Halesus radiatus

Description

Length 17 to 23 mm. A fairly large caddis with orangey brown wings that have a speckled pattering in the forks between the veins forming distinctive pale streaks. It is quite similar to H. digitatus, but the patterning does not form such distinctive pale streaks in that species (see ID Aids below).

Similar Species

Halesus radiatus can only be confused with its near cousin Halesus digitatus but the broken patches between the veins on the forewing separate radiatus from digitatus which has more or less continuous streaks.
