A very nice find of an early mine of the Small Birch Purple, Eriocrana salopiella, (Stainton, 1854). The genus name Eriocrana refers to the adults' fluffy heads and translates roughly as "woolly-headed", and it's salopiella because it was first found to be identified near Shrewsbury by Mr. Stainton.
As it's quite early in the year, it is more likely to be salopiella rather than Eriocrana sparrmannella, which is a bit more of a summer species.
