Brown Birch Slender

Local, but can be quite common
where it occurs, as a leaf-miner on birch.&nbsp;
Four main areas: Exmoor (where it may be under-recorded), the Quantocks,
around Shapwick Heath, and on post-industrial land in the east Mendips
extending into the woods on the Wiltshire border.&nbsp; Not recorded recently from Leigh Woods (last recorded 1963), but
possible it can still be found there.&nbsp;
Occasional records of adults elsewhere, presumably dispersing
individuals.

Brown Oak Slender

Local, but common where it
occurs.&nbsp; Recorded as an adult to light
and as a leaf-miner on oaks, especially (but not exclusively) on holm oak.&nbsp; Most common in seaside towns where the larger
gardens have high concentrations of holm oak, and in similar situations around
Bath and Bristol.&nbsp; Also on deciduous oaks
on old coal-tips around Radstock and Midsomer Norton.

Garden Apple Slender

Fairly common and widespread,
recorded both as an adult to light and as a leaf-miner on apple trees.
