September 8, 2016

Athripsodes cinereus (Curtis, 1834)

Athripsodes cinereus is one of 24 members of the Family Leptoceridae found in Ireland, and one of five members of the genus Athripsodes. It is a species whose larvae can be found in streams, rivers, canals and lakes, on a substratum of sand to cobble. Athripsodes cinereus has a curved case made of sand grains. The species has no preference in terms of water pH.

In temperate areas, Athripsodes cinereus has a univoltine (one generation per year) reproductive cycle, and lives for up to one year. In terms of feeding, this species mainly a predator, with shredding and gathering also undertaken.

Defining features of the larvae of Athripsodes cinereus include a mesonotum with dark, curved posterior-lateral projections, mandibles no more than twice as long as wide, a triangular ventral apotome, no dagger-shaped setae on the anterior face of the 3rd leg trochanter and femur, the ventral edge of the tibia of the 1st leg with only a single strong setae at the distal corner, no pale gap in the dark posterior ridge of the head capsule made by a subocular ecdysial line and muscle attachment spots visible as clearly darker spots on the mesonotum, pronotum and parts of the head capsule.

The adults of Athripsodes cinereus can be found on the wing from June to November.
