Round-winged Muslin - Thumatha senex
Wingspan 15 to 20 mm. The sparsely scaled wings of this moth give it a thin, papery appearance.
Inhabits marshes and fenland.
The adults fly in July and August, and are attracted by light.
The larvae feed on lichens, especially dog lichen, as well as various mosses.
Distributed widely, though not commonly, throughout a large part of Britain, it is scarcer in Scotland and Ireland. In a recent survey to determine the status of all macro moths in Britain this species was classified as local.
Occasional in Leicestershire and Rutland. L&R Moth Group status = C (very scarce resident or rare migrant).
