Late Post- Friday`s trapping ( 4.10.13) at Pwll

Was too tired and still aching after my escapades down that ravine on Friday to post yesterday. Nevertheless, I`d put out three traps that night - an MV at home and two actinics near Cilymaenllwyd, Pwll.
The MV caught a similar batch of moths to Thursday night`s actinic at Tyrwaun, with 1 vestal (presumably a re-capture of one of the two caught on Thursday) and the usual suite of autumnal moths. Four rush veneers, as well as the more usual silver ys, represented the migrants. It`s getting really seasonal now, with the last of the passage chiffchaffs passing through and the first passage/wintering goldcrests arriving.
One of the Cilymaenllwyd traps was placed near a mature hybrid lime tree (hoping for orange sallow - failed, with only the common sallow spp. present), but here there was my first `November moth` Epirrita sp. a flounced chestnut (a slightly local autumn species) and a chestnut. Photos of the last two given below.

The other Cilymaenllwyd actinic was placed under a mature beech clump, where I was targeting barred sallow, but again failed. There was, however, quite an array in this trap, including a vestal (this time a very pale individual) as well as other moths such as green-brindled crescent, pink-barred sallow etc. Again, there were the difficult-to-identify `November moths`, one of which I took home to photograph (see below) and also the season`s first mottled umber (again photo below). Winter is on the way!
I also had rather a rare beetle - Platycis minutus - a small, bright red species that is mostly confined to southern parts of England and SE Wales. It has also been recorded at Dinefwr Park (Llandeilo) and I had it at Tyrwaun, Pwll back in 2005. It is only c 0.75cm in length and it is associated with rotten heartwood of beech and other trees (my 2005 specimen was found on old cherry logs). There is a much rarer relative (P. cosnardii) that is found in the Wye Valley; it has a reddish-brown pronotum, rather than being all-black, as is the case with minutus). Photo below.

I also had a micro (photos below) at Cilymaenllwyd - can anyone advise me as to its identity please? -thanks. Near to the beeches are amenity plantings of other tree species, in case it`s relevant. Is it possibly Ypsolopha sequella?

It`s still worth persevering with moth trapping, both for late season residents and the chance of migrants - so keep at it!


  1. Yes, Ypsolopha sequella. An Acer feeder that doesn't appear to be on the Carms list!

    Well done on another Vestal. I think it's just as likely your home one won't have been a re-trap. Mine here last night wasn't.

  2. Thanks Sam. I note that the NBN maps show it in west Glam.
