Scarce Maple Pigmy

A leaf-miner on Field maple and Norway maple.&nbsp; Essentially a south-eastern species, it has been expanding its range in recent years, presumably in response to the warming climate.&nbsp; This range expansion has been slow to reach Somerset, and has only done so in the last few years, with only isolated records at this point.&nbsp; This is in contrast to Gloucestershire immediately to the north where the moth is well-established across much of the county and the mines are easy to locate.&nbsp; No doubt it will become much commoner in the near future.

Nut-tree Pigmy

A leaf-miner on hazel and hornbeam; the former plant is by far the commoner and the records reflect this.&nbsp; The moth is widespread and common, occasionally proving to be locally abundant.&nbsp; Gaps in distribution probably result from under-recording, though both foodplant and moth may be absent from the alluvial areas of the Levels and the more barren parts of inland Exmoor.

Scarce Sloe Pigmy

Only recorded from the Porlock area extending west at least to Embelle Wood.&nbsp; Although not seen since 2006, it is unlikely to have been looked for.&nbsp;&nbsp;
