Stenophylax permistus McLachlan, 1895

Stenophylax permistus is one of 39 members of the Family Limnephilidae found in Ireland, and the sole representative of the genus Stenophylax. It is a species whose larvae can be found in small, temporary waterbodies, such as drainage ditches, woodland streams and marshes, in slow-flowing and standing water. Stenophylax permistus has a straight case made of butted leaf fragments. The larvae have no preference in relation to pH and can be found in brackish waters.

The feeding ecology of the larvae of Stenophylax permistus is divided between shredding and gathering.

Characteristic features of the larva of Stenophylax permistus include a prosternal horn, dorsal protuberance on the 1st abdominal segment, antenna midway between the eye and the anterior head margin, gills with only single filaments, two anterior-median sclerites on the metadorsum, mandibles with teeth along the edges, no setae proximal to the large primary seta on any femur of the 2nd and 3rd legs, no setae anterior to the 1st abdominal lateral protuberance, which either has no sclerite in its posterior region or 1-3 small sclerites that lack setae, but may have a large central hole, spinules on the head restricted to a small patch behind the eye, and additional setae on the anterior face of at least three of the four femora of the 2nd and 3rd legs.

Adults of Stenophylax permistus can be found on the wing from April to October, with a summer diapause.
