The Double-striped was on the wall nearby, and the Brindled was on one of the plastic sheets that form the slippery slope to the interior. Clearly, moths do not find it all that slippery after all.

On the same night, the bigger and more powerful Robinson trap was put out on West Wickham Common. Unfortunately its top blew off towards the end of the night. Perhaps because of this, there were only two moths present, both of them Oak Beauties. (For scale, that's the edge of my thumbnail at top left.)

Anyway, we didn't see an Oak Beauty here last year, probably because we started trapping after their usual flight time, so this is an addition to the species list. They are not restricted to oaks as larval food plants, but this site is on the edge of an oak wood, so these specimens probably grew up feeding on their namesake.
