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.

hannoverella and dodecella

My first garden Meadow Brown of the year was on 22nd June, along with a Common Nettle-tap Anthophila fabriciana.  That night the best moth in the trap was a New Poplar Pigmy Ectoedemia hannoverella - a new species for me (or so I thought - read on for a 2018 edit).  Some seem to frown upon even attempting to identify Stigmella/Ectoedemia species in adulthood (the leafmines are generally much easier) but this one keyed out quite smoothly and the genitalia were spot on.  There aren't any records of adults in Norfolk and compared to other Nepticulidae I've identitfied not all that many records of leafmines either.  Most records are from the Brecks and the Fens with just one record from Dereham being relatively close.  However, it's a recent arrival to the UK and is spreading so I shouldn't be surprised if they're all over the county before long.

New Poplar Pigmy Ectoedemia hannoverella (male, gen det), North Elmham, 22nd June - or not: see below*

* Edit 2018: OK, there's a reason why as I said above some frown upon attempting to identify these in adulthood.  I got a bit suspicious after having two more in 2017 and another in 2018 which seems a lot for a Poplar-feeding species given the distance from here to the nearest Poplars.  Having looked into it a bit more it now seems possible - indeed likely - that they are not hannoverella but Spotted Black Pigmies Ectoedemia subbimaculella.  I cannot rule out hannoverella, nor the Holm-Oak species heringella as both the external appearance and the genitalia are very similar between all 3 species, but as there is an Oak tree close by (subbimaculella feeds on Oak) and no Poplar or Holm-Oak very close I think subbimaculella is most likely.  Not entirely sure why I overlooked this as a possibility - probably because most of the photos online show much better patterned individuals than any of mine.

A Pine Groundling Exoteleia dodecella was new for the house and only the third time I've seen this species.
