Least Thorn Pigmy

A leaf-miner on Hawthorn.&nbsp; Fairly common and widespread, though with gaps in its distribution, some of which are likely to reflect an absence of recording.

Dropwort Pigmy

Current thinking is that this is a single species, mining Dropwort Filipendula vulgaris&nbsp;and Meadowsweet Filipendula ulmaria.&nbsp; At various times in the past, the species has been split and the Meadowsweet-feeding examples have been considered a separate species, S. ulmariae.&nbsp; In Somerset, the species is only known from a mine on Meadowsweet at Rowberrow Warren in 2019.

Grey Apple Pigmy

A leaf-miner on Apple Malus&nbsp;spp.&nbsp; There are few records from the county, and it is probably very under-recorded rather than rare.&nbsp; There is a concentration of records around Cheddar and Winscombe, and a scatter elsewhere.

Stigmella incognitella

Grey Apple Dot
