Green caddisless fly fishing
The sedge (Thricoptera) family of Ryhacophilidae is a world-wide spread insects group of high profile to fly anglers. The family is characterised by a green or greenish colour at the stage of larva, that makes it possible to imitate this large group with very few specific patterns. Based on the lateral gills appendages, some literature divides the genus Rhyacophila in 3 sub-genera: Hyporhyacophila, Rhyacophila (Pararhyacophila) and Hyperrhyacophila. In Europe there are 83 species so far classified.
