Hornbeam is a tree that’s somehow escaped my attention but, at this time of year, when its leaves turn gorgeous and vibrant shades of yellow, I can’t help but notice how widespread it is and, while admiring its autumn colour, I’ve also spotted some leafmines on its leaves.

211129 Stigmella microtheriella (1)

Reading the mine description on the British Leafminers website, I thought I had found Stigmella microtheriella (egg laid, so mine starting, on or near a vein but not in the axil) but, as there was potential confusion with another moth, Stigmella floslactella, I checked with the experts. Rob, one of those behind the British Leafminers website, kindly confirmed that my identification was correct and also commented that ‘Although S floslactella is said to mine Hornbeam I don’t know anyone who has found it on that host. It’s a very doubtful record.’ Now I – and you, if you see mines like these – can record them as Stigmella microtheriella with confidence!
