Local in woodland throughout most of England and Wales. In Hampshire widespread but apparently uncommon, although probably overlooked; very rare on the Isle of Wight and the imago was recorded for the first time in Shanklin, 2015. Wingspan 12-15 mm. Fairly unmistakable in appearance. Larva feeds on fungi and dead wood of Alder, Elm, Oak, Beech and Hawthorn.
