Recent Leafmines

I've managed a few more trips out to sites around Oxford, looking for leafmines and larvae in recent weeks. Firstly to Wytham Woods on 31/10 where the highlight was more mines of Stephensia brunnichella on Wild Basil. This seems to be quite widespread on any unimproved calcareous grasslands around Oxford, and I found more on a verge by Bayswater Road and then at Sydlings Copse on 06/11.

Here I found just over 50 species of leaf miner and larvae in an enjoyable morning. The main highlight was the red data book Stigmella filipendulae on Meadowsweet (ID confirmed by John Langmaid) in the fen area of the site.

I also found a few mines of Parornix fagivora on Beech, and a case of Coleophora albitarsella on Ground Ivy, which were both new ones for me. Other notables were Ectoedemia angulifasciella on Dog Rose, Ectoedemia rubivora on Bramble, a Thiotricia subocellea case on Marjoram and a nice variety of birch-feeding stigmellas.
