Species profile: Limnephilus affinis

July 13, 2017

Limnephilus affinis Curtis, 1834

Limnephilus affinis is one of 40 members of the Family Limnephilidae found in Ireland, and one of 24 members of the genus Limnephilus. It is a species whose larvae can be found in pools, lakes and slow-flowing ditches, as well as brackish habitats such as saltmarsh pools and lagoons. Limnephilus affinis has a straight case made from abutted or overlapping pieces of plant material, or may be slightly curved where sand grains are incorporated. Its larvae can occur in brackish water.

The feeding ecology of the larvae of Limnephilus affinis is predominantly shredding, with some predation and grazing.

The larvae of Limnephilus affinis cannot be reliably separated from the larvae of Limnephilus incisus, so adult material is required.

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