Scarce Thorn Pigmy

A rare leaf-miner of hawthorn, with a scattering of older records and not recorded in the county since 2004.

Barred Elm Pigmy

A leaf-miner on elm, occurring on hedgerow elms as well as trees, and therefore has escaped the worst effects of Dutch Elm Disease.&nbsp; Care needs to be taken distinguishing larva or mine from the somewhat commoner S. lemniscella, which also mines elm - in S. ulmivora, the larva is green, not yellow, and exits the mine on the underside of the leaf, not the upperside.&nbsp; The moth is reasonably common and well-distributed in the east of the county, and more scattered elsewhere, though this may reflect under-recording.

Plain Elm Pigmy

A leaf-miner on elm and by far the scarcest of the three Stigmella species using this plant, though still not exactly rare.&nbsp; It is scattered in distribution across the county, with clusters of records around Orchard Wood/Thurlbear south of Taunton, around Hinkley Point (not yet mapped) and in the Porlock area.&nbsp; It is widely if diffusely recorded around Frome and Radstock, where there are many elm-rich hedgerows.
