I dream of catching Oak nycteoline every time we trap in oak woodland but I have never caught one. This one was recorded last night by Pete Skinner, along with Twin-spotted quaker, Early grey and Brindled pug.
There are only 20 county records for Oak nycteoline, 11 of them since 2000, and most recently at Aberporth in 2014. It over-winters as an adult reappearing in early Spring but only occasionally comes to light. The moth is very variable in appearance but this one is very similar to the one caught on 9th March 2014 (see photo on the blog for that date).
