Something to look out for in Carms

I'm sorry to post Monmouthshire sightings here, but I'm still a Carms moth'er at heart and it's useful to give people a heads-up for expanding species.  As far as I can see, the mines of Stigmella aceris that I spotted on a Norway Maple on my way from the NRW Monmouth office to Lidl are the first Welsh records.  This species has spread rapidly north-westwards through Britain and has been in Gloucestershire for a few years.  There's a Phyllonorycter tentiform miner on Norway Maple that is already known from Carms, plus an Ectoedemia that mines the 'keys' and which is present in VC35.
The last time I trapped was in the Dingestow garden on Saturday night.  150+ individuals of 21 species was a good haul for autumn, and they included a couple of gorgeous Barred Sallow (not yet known from Carms) and a very well-marked Pearly Underwing.  An attempted Ivy check a couple of nights later was unproductive, but there were a few nice moths on Blackberries.


  1. lovely photos! Haven't seen Barred Sallow in a long time.

  2. .....Have n`t seen a barred sallow EVER! (though I have tried some obviously failed targeted trapping at beeches in Stradey Woods). Well done.

  3. Sam - do you reckon that barred sallow is using field maple or beech at Dingestow? Both trees occur in Carms, beech as a common estate tree etc and field maple as a rather rare woodland species (though it`s now common as a roadside/amenity planting).

  4. Potentially both, Ian - we've got some big parkland Beech here including in the sight-line of where I caught these recent 2, but there's lots of Field Maple in nearby hedges and woods. I've only had Mocha in the garden once, whereas it's regular in the woods, whilst Barred Hooktip is quite frequent in the garden. On balance, I'd say we get more Beech than Maple moths here.
