Hensol Forest, Saturday night

I was frustrated not to be able to get out trapping away from the garden during last week's hot spell, so had to content myself with a session on Saturday night - by which time the heat had gone and a chilly wind was blowing. As a result I was surprisingly pleased with the result - 69 species in 3 hours in mixed woodland at Hensol Forest. The temperature held up at 13C throughout, and it stayed cloudy - which no doubt helped as the moths kept arriving throughout.

I used the 'three card trick' of 125W MV, 6W actinic and my newly acquired 3W LED trap (electrics supplied by Paul Batty in Sheffield, 'retro-fitted' onto a Heath trap body). The LED trap performed slightly better than the 6W actinic, and contained the night's best moth - Epinotia subocellana (6th VC record I think), as well as a Little Thorn.
Other minor highlights included Waved Carpet, Barred Umber, Map-winged Swift, Green Silver-lines, Orange Footman, Square Spot, Dwarf Pug, Grass Rivulet, Alder Moth,  Epinotia tedella, Ancylis mitterbacheriana, Argyresthia conjugella, Mompha raschkiella and Cydia fagiglandana.

The species list is building nicely now, with Sloe Pug being the latest in the 'more interesting' category.
I've also got a better photo of the Cydia cosmorphorana from last week:

Merthyr mawr today.

            At least 50 Adela croesella were flying around the Buckthorn tops.

             Cauchus rufimitrella

             Notocelia cynosbatella.
Four spotted footman larva.

Stigmella trimaculella

The recent hot spell brought just one new species for my garden list, the tiny but distinctive Stigmella trimaculella. It has slightly odd markings, but I don't think it can be anything else. I've seen the leaf mines of this species on the poplars down by the Taff, about 500m away.

Graig, Llantrisant

A couple of weeks ago I was at The Graig and saw what I thought was Eucosma aspidiscana in an area with lots of golden-rod (the foodplant), but it flew off before I could net it or get a photo. I was back at the site today to look for Anania funebris, and in the same spot were two Eucosma aspidiscana flying in the sunshine. I managed to net one this time.

As far as I know this is the first VC41 record, just a few days after Dave had another tortrix new for the county less than a mile away!

I also saw one Anania funebris (too fast for a photo), eight Small Pearl-bordered Fritillary, and several Cauchas fibulella.

Endothenia nigricostana query

Prowling our garden in Creigiau this afternoon and spotted several Diamond-backs, but none would pose for a picture, and managed a 'grab-shot' of a Nettle-tap's bottom. However, the main event was spotting Endothenia nigricostana at the back of one of the flower beds. I did see these last year, and had left a clump or two of woundwort in the beds to see if they would return - hopefully they  have.
