Species profile: Setodes argentipunctellus

January 15, 2017

Setodes argentipunctellus McLachlan, 1877

Setodes argentipunctellus is one of 24 members of the Family Leptoceridae found in Ireland, and the only member of the genus Setodes. It is a species whose larvae can be found on exposed stony lake shores, but, in Ireland, has only been found in the Killarney Lakes, Co. Kerry. Setodes argentipunctellus has a slightly curved case made of sand grains. The species has no preference with regard to the pH of the water.

In temperate areas, Setodes argentipunctellus has a univoltine (one generation per year) reproductive cycle, and lives for up to one year. In terms of feeding ecology, the larvae are thought to be grazers.

Defining features of the larvae of Setodes argentipunctellus include antennae at least six times longer than wide, a mesonotum without dark, curved posterior-lateral projections, mandibles no more than twice as long as wide, and anal prolegs with two rows of strong spines.

The adults of Setodes argentipunctellus can be found on the wing in June to August.
