Narrow-barred Pigmy

A miner of roses, both wild species and garden cultivars.&nbsp; It is difficult to record, the adults requiring dissection and the leaf-mines separable only with difficulty from the much commoner S. anomalella.&nbsp; It is clear that it occurs within the county and is rarer than S. anomalella, but it is difficult to interpret the records further.

Buckthorn Pigmy

A miner of buckthorns, both Common Buckthorn Rhamnus cathartica and Alder Buckthorn Frangula alnus.&nbsp; Both foodplants are local and often scarce in Somerset.&nbsp; Mines can often be easy to find and frequent on an individual shrub, and the map may well give a more accurate picture of this species' distribution than is usually the case for leaf-miners.

Rose Leaf-miner

A leaf miner of both wild rose and garden cultivars.&nbsp; It occurs right across the county and gaps shown in its distribution are likely to stem from under-recording.&nbsp; Unlike many Stigmella species, there are often several mines in close proximity on an individual plant.&nbsp; Numbers seem to fluctuate from one year to the next.&nbsp;&nbsp;
