Quick update...

Like Chris, I too trapped last night and similarly, whilst the numbers and variety (c 55 spp.) were good, there was nothing hugely exciting in the catch. Of moderate interest, a scruffy old lady turned up (I`ll avoid any puns!) but it was not up to a photograph or two, scuttling quickly off into vegetation after I`d taken a very poor photo.
I paid a short visit to a local allotment yesterday afternoon in the hope of finding a leek moth Acrolepiopsis assectella, or signs of its feeding, but I failed. Chris Manley has had it not far away in Glamorgan and I`d hoped that it had reached Llanelli. I`ll have to wait.
In the tiring heat, I made a short walk along the banks of the urban Afon Lliedi noting some leaf mines en route, thinking that I`d better do some practical `swotting-up` before the leaf mine course at Cilgerran next month.
Several leaf mines were found including what I think is Phyllonorycter quercifoliella on oak, it being thought to be this species rather than the similar mine of P. roboris as the former has a single crease (visible in the photo below) in the lower epidermis of the oak leaf.

  1. The Oak Phyllonorycters are pretty difficult as mines. You really need to open the mine and look at the pupa to see how it's attached, so as to separate the common P quercifoliella and P harrisella. All the others except P messaniella are scarce/rare/unknown in Carms.
