January 13, 2017

Ylodes reuteri (McLachlan, 1880)

Ylodes reuteri is one of 24 members of the Family Leptoceridae found in Ireland, and the only member of the genus Ylodes. It is a species whose larvae can be found in brackish water, including coastal marshes, on a substratum of living plant material, occurring only in standing water. Ylodes reuteri has a straight case made of a spiral of plant material. The species has no preference in relation to the pH of the water.

In temperate areas, Ylodes reuteri has a univoltine (one generation per year) reproductive cycle, and lives for up to one year.

Defining features of the larvae of Ylodes reuteri 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, anal region lacking toothed plates or rows of strong spines on the prolegs, 1st abdominal lateral sclerite without a dark line on the posterior projection, 3rd leg with one long setal fringe to enable swimming, 1st leg tarsus without setae on ventral edge and trochanter of 1st leg with more than two short, pale ventral setae and more than one dorsal seta.

The adults of Ylodes reuteri can be found on the wing in July.
