Away from home, now is a good time to look for leaf mines. Neale has kindly confirmed that this is the mine of Trifurcula cryptella, found after a bit of searching on Greater Bird's Foot Trefoil at Langford Heathfield. It appears to be the second county record (and first for VC5) of this nationally scarce A moth, with the other record coming from Shapwick, but it's probably worth looking for in other damp woodland locations.

At Dead Woman's Ditch this week, I also found several mines of Stigmella myrtillella, a Bilberry feeding specialist that is also probably quite under-recorded. Most of the mines I found were on lush plants growing under the shade of the oaks rather than on the open heathland. Also here were Twin Spot Carpet, Holly Tortrix, Argyresthia goedartella and conjugella, Epagoge grotiana, Cydia ulicetana, Monochroa cytisella and a Silver Y, as well as the mines of Lyonetia clerkalla and Phyllonorycter sorbi on Rowan.

Yesterday I headed down to Hurlstone Point and Porlock Marsh for a wander, and was pleased to find lots of the spiral mines of Enteucha acetosae on the point, already recorded here by James McGill a few years ago.

Down on the marsh Bucculatrix maritima mines were abundant on the Sea Aster, along with several Eucosma tripoliana and a brief view of a male Red-Veined Darter. The highlight came in Bossington village though, with mines and adults of the lovely little Cosmopterix pulchrimella abundant around Pellitory of the Wall, which appears to be the second record for Somerset. This is another species that is on the march and worth looking out for, seemingly preferring coastal sites in other parts of its English range.
