Shaded Fan-foot Herminia tarsicrinalis
Wingspan 28-32 mm.
A very retiring species, which occupies bramble (Rubus) thickets in deciduous woodland. It very rarely moves far from these bushes, and as a result of this was only discovered as a British breeding species in the early 1980's.
It has now been found in various parts of East Anglia, and the best means of recording it seems to be to place a light-trap deep into the bramble bushes.
It flies in June and July, and the larvae (at least on the continent) feed on withered leaves.
