The main highlight was the nationally scarce B leaf miner Stigmella poterii on Salad Burnet - I found a couple of definite (tenanted) mines on the main slope, while a few others elsewhere may be Ectoedemia angulifasciella (of which there were a few mines on Wild Rose). Dave says this may well be new to VC23.

After a few ambiguous mines, I also found a Trifurcula headleyella mine, kindly confirmed by Andy Banthorpe, who found the first for Bedfordshire this year. This is a proposed RDB species that feeds on Self-Heal.

There were also lots of mines of the Nb Stephensia brunnichella on Wild Basil - I've searched for these several times before, but never found them (oddly, just the stunning adults resting on the foodplant), so very pleased to see them.

The final highlights were both on Thyme - a Coleophora lixella case, and a young Thyme Plume larva. Other species of interest were Strophedra weirana on Beech, Bucculatrix frangutella on Alder Buckthorn, Coleophora gryphipennella on Dog Rose, Euspilapteryx auroguttella and Ectoedemia septembrella on St John's Wort, Mompha rashkiella on Rosebay Willowherb, Coleophora argentula cases and a Tawny-Speckled Pug larva on Yarrow, and a Parornix torquillella larva with its black legs on Blackthorn. Lots of Silver-Spotted Skipper eggs found on Sheep's Fescue tussocks too (including one cluster of 14!).
