A diary of my mothing activity covering highlights and photos from my moth trapping activities. Mainly Norfolk (UK), occasionally beyond. I may mention other wildlife sightings here, especially insects, but for birds see my birding diary.

Another new Stigmella

An Anthrenus fuscus in the house was new for the year on Monday 21st.  These mascarade as Varied Carpet Beetles Anthenus verbasci but there are quite a few differences when you look closely (such as the blacker scales and the very different structure of the antennae).

The highlight from the moth trap that night was a Common Oak Pigmy Stigmella roborella.  Although common, like most Stigmella speices they are mostly recorded as leafmines and adults are rarely reported.  This was my first, keyed out accurately using the excellent Kleine Vlinders key and confirmed with gen det.

Also new for the year were Fen Flat-body Depressaria ultimella, Scorched Carpet and 2 Treble Lines, plus the caddisfly Cyrnus trimaculatus.  Other moths were Bee Moth Aphomia sociella, Common Plume Emmelina monodactyla, Grey Pine Carpet, 2 Green Carpets, Mottled Pug, Common Pug, 2 Brimstone Moths, Waved Umber, Coxcomb Prominent, Buff-tip, Orange Footman, 2 White Ermines, Heart and Dart and 2 Shuttle-shaped Darts.

The following evening looked a bit better for moths so I headed down to the meadows and set up two lights.  No sooner had I got the second one on and the generator packed up as it had run out of oil. I didn't have any spare oil so that was the end of that.  In the short time the first light had been on it had caught a Common Swift, new for the site, and I also added Common Toad to the site's amphibian list.

There wasn't a vast number of moths in the trap the following night but Turnip Moth and Shears were new for the year, and a Flame Carpet was a much finer specimen than the one last week.
