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.

Carpatolechia fugitivella - first modern county record

On Thursday 25th June I caught 82 species of moth at home.  I've only just finished sorting out those that needed dissections and among these was a Gelechiid I didn't recognise.  I eventually narrowed it down to the genus Carpatolechia and found two species that can share the general appearance.  I came across a similar fugitivella first and the description in MOGBI checked out perfectly.  In particular its closest confusion species (notalella) was easily eliminated because notalella lacks the scale tufts that were evident on mine.  But fugitivella hasn't been recorded in Norfolk since the 1800s so I needed to check other species more carefully.  In doing so I came across a picture of decorella which looked extremely similar.  The references seem to think this species is easily identified by a dark bar on the costa near the base.  Well mine had a small oblong dark mark along the costa near the base, but it didn't look quite as long as supposed to be shown by decorella - and fuitivella also shows a dark spot here, so I wasn't quite sure.  The detailed description of decorella in MOGBI seemed to have some anomalies, like mine didn't show furrows on segment 2 of the labial palpus when viewed through the microscope.  Fortunately the genitalia diagrams here and on the Dissection Group looked significantly different, at least in one respect (very long processes reaching the tip of the uncus in fugitivella) and on dissection mine matched Elm Groundling Carpatolechia fugitivella perfectly, the first Norfolk record for 116 years!  Shame this insect had been too active to let me photograph it out of the pot - here's the best I could manage while it was alive...

And for those who do dissections, here are its bits.  You can see one of the long processes left of the uncus but the other one broke off during preparation.
