Also at dusk on my Red Valerian were Silver Y and Treble Bar / Lesser Treble Bar (not sure which, I saw it but didn't capture it).
A light left on a timer at the Chiltern Open Air Museum added a few to the year list; Pseudargyrotoza conwagana, Aleimma loeflingiana, Ephestia unicolorella (formerly parasitella), Setaceous Hebrew Character, Reddish Light Arches, Beautiful Golden Y and Snout were new for my year list.
Reddish Light Arches
Also, can anyone confirm for me if this is Scoparia pyralella or something else?
Finally, and I know this is an awful pic, but can anyone tell me what this is? It sits like a Caloptilia-type when it's indoors, but as soon as I try to photograph it, it sets off. I think this pic at least shows the wing pattern!
