Small Lappet Phyllodesma ilicifolia
Wingspan 35-40 mm.
Possibly now extinct in the British Isles, this species was formerly found in moorland and woodland habitat in parts of mid-England and the south-west.
There have been no confirmed records since the 1960's, but it is considered to possibly still remain undetected in some areas.
The adults would fly in April and May, and the larval foodplant was bilberry (Vaccinium myrtillus).
