White-barred Alder Pigmy

A leaf-miner on alders.&nbsp; Extremely difficult to identify, either via dissection of the adult or a photo of a tenanted larva in the mine.&nbsp; It is likely to be more widespread than shown.

Small Birch Pigmy

The larvae of this moth make gallery mines on birch.&nbsp; Local and scattered in upland west Somerset, though undoubtedly under-recorded there.&nbsp; Much more frequently recorded in the wetlands around Shapwick, widely distributed in woodland and post-industrial sites around Frome and Radstock, and with populations on amenity plantings of birch in and around Bath.

Short-barred Pigmy

A leaf-miner on birch.&nbsp; Widely scattered records across much of the county, the current distribution map probably reflecting recording effort.
