August was rather a quiet month in comparison to July, but a few nights produced interesting moths. Highlights at Dingestow were the second Jersey Tiger for the site on 20th August and Dingestow's first Crescent and 8th Bulrush Wainscot on 29th August.

From Ian Rabjohns, trapping near Penallt: Recent September and early October catches have been very slim, but and interesting addition on Friday 8th was this pair of mating L-abum wainscot. The size difference in this pair at least is clear with the female on the right. On the underside the male has a distinctive black patch.

Langmaid's Yellow Underwing (Noctua janthina) was separated from Lesser Broad-bordered Yellow Underwing (Noctua janthe) in 1991 and was recorded new to Britain (by John Langmaid, hence the name) shortly afterwards. Initially it appeared to be an occasional migrant/vagrant to Britain, but in the last 15 years it has been seen annually in many parts of south-east England and is clearly resident. The first Welsh records came from Montgomeryshire in 2009 but very few have followed. I have been aware of its likely appearance at Dingestow for several years, but checking the hindwings of Lesser Broad-bordered Yellow Underwing for the characteristically extensive black border of Langmaid's is very difficult on live specimens.
The Dingestow Court MV trap on 21st-22nd July 2021 held three Noctua: one of which (the left hand individual in the photo above) appeared significantly shorter- and broader-winged than the other two. Crucially the shorter-winged one appeared to have very little yellow on the hindwing. Failed attempts to photograph its hindwing when it was alive eventually resulted in it escaping in my kitchen and vanishing for several hours. Luckily it was relocated, allowing conclusive examination of the male specimen showing it to be Monmouthshire's first (confirmed) Langmaid's Yellow Underwing.
While the country struggled to sleep during nearly a week of 30 degree daytime temperatures and >15 degree nocturnal minima, the moths went wild. Successive 04:30 starts played havoc with my sleep, albeit with lie-ins after late night 00:30 sessions with the generator on two nights, but it was well worth it. Five moths new to Dingestow came to my lights between 14th and 22nd July, taking the area total to 991 species. Highlights were:
14/7 Penyclawdd Wood: 1 Blackneck* (3rd Dingestow record), 1 Argolamprotes miceella (2nd), 1 Catoptria margaritella* (2nd), 2 Eudemis profundana* (2nd), 1 Mompha ochraceella* (3rd), 1 Ypsolopha alpella (3rd)
