Sharp frost but no migrants on site & with strong sunshine no offshore observations. It's the time of year when we need to get this years moth list going. To cold for moths but mines of Stigmella suberivora & Ectodemia heringella are abundant on the Holm Oaks to the point where it's difficult to find a leaf without either or both. Also noted Stigmella aurella on Bramble. All three are abundant on site but are far easier to identify by their leaf mines than as a flying moth which are little more than flying specks of dust.
