Recent daytime mothing

As the night-time weather has not been ideal for trapping, I`ve been doing some daytime mothing instead - leaf mining or just keeping my eyes open to see what is around. One site that I visited yesterday (21/5) is an area of dry open ground and scrub habitat next to the Loughor Estuary at Bynea. Diurnal moths seen include small yellow underwings and treble bars; my attempt to photograph the latter made difficult due their nervousness and sensitivity to the smallest movement. I nearly managed to photo one individual, but a scuttling cantharid beetle scared it off!

The scrub birches on part of the site held the leaf miner Eriocrania sangii, easily identified by its grey caterpillars.

A nice surprise were two individuals of Adela cuprella, one flying near some dogwood blossom and the other resting on scurvy-grass on the upper saltmarsh! A good butterfly find was a single brown argus; its larval food-plant stork`s-bill grows at the site.

This Coleophora on hazel at Bynea may prove to be of interest (photo immediately below):


An earlier visit to Troserch Woods yielded - among other common species - Micropterix aureatella on bilberry.

There have been quite a few sightings of brimstone butterflies around recently at several Llanelli/Burry Port localities. Yesterday evening at North Dock, Llanelli, I also had diamond-back moths in double figures, so obviously there been an influx. The weather is getting cloudier from tomorrow, so light trapping could well be productive.

  1. I think your Adela is just reaumurella - it's too late in the season for A cuprella and A reaumurella has been on the wing for a couple of weeks here. Sorry!

  2. Thanks Sam. I did consider reaumurella (which has been on the wing here too for c. a fortnight) but, considering the extra dry habitat and the fact that I`ve had it on similar dry situations at Pembrey, plumped for cuprella. Also, I`ve previously had confirmed cuprella in mid May. The coppery colouring also pushed me towards cuprella. The MBGBI say `bronzy golden tinged with copper` for cuprella and `bronzy green` for reaumurella and I can`t see any greeness in my photo or with the live moth (since released), hence my assumption that it was cuprella.
    However, I have a photo - taken about a week ago - of a female reaumurella and that too looks coppery rather than bronzy green! It`s safer perhaps to go for reaumurella.
