Bilberry Pigmy

A leaf-miner on bilberry.&nbsp; In Exmoor most commonly recorded on bilberry under oak in the Horner Wood and Porlock areas, but does occur elsewhere, such as along roadside verges at Comerslade.&nbsp; There are several records from Quantock Common, but none from elsewhere on the Quantocks.&nbsp; Doubtless new sites remain to be discovered in both areas.&nbsp; It is unknown from the Blackdowns and from VC6.

Small Beech Pigmy

A leaf-miner on Beech, very common to abundant across the county where its foodplant occurs, and may be absent from parts of the Levels owing to lack of foodplant.

Sallow Pigmy

British specimens of Stigmella salicis are currently understood to relate to two separate, as yet undescribed, species, referred to as cluster 1 and cluster 6.&nbsp; The mines, on sallow, can be distinguished by the placement of the egg, on the underside of the leaf for cluster 1 and on the upperside for cluster 6.&nbsp; Both species have been recorded right across the county, from near sea level on the Levels to some of the highest land in Somerset on the Exmoor moorlands.&nbsp; When recording this species, please indicate on which side of the leaf the egg was placed; the record will then be referrable to the correct species once they have been formally described.
