Northern Rowan Pigmy

A miner on Rowan, which is absent as a naturally-occurring species from large areas of the county.&nbsp; Unsurprisingly, its distribution is restricted to Exmoor and the Quantocks where the foodplant is commonest.&nbsp; It is probably under-recorded here.

Purple-shot Pigmy

A leaf-miner on hawthorn, common in the east of the county, less well-recorded (and possibly scarcer) elsewhere.

Common Thorn Pigmy

A leaf-miner on hawthorn, appearing to be fairly common on the Mendips and northwards, and on the Poldens; more scarcely distributed, and maybe under-recorded, in the south and west of the county.
