On 28th August I had this moth at the obs which Steve Gale identified as a Dewick's Plusia. I checked with Derek and this is a first for Beddington!
I've only been mothing for a couple of months and haven't even got a proper moth trap yet- just been using a garage light I bought from Lidl for a fiver. I've ordered a trap which should arrive tomorrow.
That is the third first for Beddington now from the obs (in two years)- Common Crane, Black Kite and now Dewick's Plusia.
