Tethea or (Denis & Schiff., 1775)
Description: Wingspan 38-43mm. Adults can be distinguished from other lutestrings by the four medial bands across the grey-coloured forewings and the yellow stigma.
Flight Period: Adults have been recorded from as early as mid-May until late July.
Status: Local, and only reliable recorded from Fermanagh. Here it has been recorded from the Crom Estate and surrounding area in the south of the county and from Garvary Wood and Lusty More Island on Lower Lough Erne in the north west.
Ecology: A scarce species associated with woodland and lakeshore habitats in Fermanagh where old established poplar and aspens grow. This species may be more widespread than records suggest. Iinvestigation of other shoreline habitats where the foodplant exists may yield further populations. The larva feed at night on the leaves of aspen. It spends the winter months in the pupal stage.
