Kent Black Arches, Barry, July 16th

A Kent Black Arches which is new for us and the garden in Barry. No records in TMOG or the new website database either?

I am not entirely sure whether to record this for the 16th or the 15th as it fluttered in the corner of my eye whilst I was preparing the moth trap last night. Therefore it was either hiding in the trap undiscovered from the previous night or on the lawn. After a short chase through the workings of my son's trampoline and the sweet peas I finally managed to pot it.

I just tried to get a better picture but it's very excitable so will have to try after work. Paul said one was taken last week at Kenfig so seems to be a moth on the move?

Last night overall was probably a bit moon-y after the eclipse and a little colder than previous nights so numbers were down a bit but there was a nice Swallow-tailed moth in with the usual mixture.

Mompha terminella

Stumbled across this Mompha terminella at Garnwen [SS8392], Maesteg on 6th July 2019. Not a good photo, but enough for ID.  Looking at the data on the new web site there have been only 2 previous Glamorgan records, one of which was a leaf-mine.

Small Marbled, Barry, July 4th

Thursday night was quite good for numbers and new species for the year and I thought I might have a NFG in this little 'micro' which had survived the sparrows and blackbirds sat on the corner of the trap. After trawling through the micros book fruitlessly I realised it was a Small Marbled and not a micro at all!

Also from the same night we had two Round-winged Muslin NFG and this morning there was a single Lunar-spotted Pinion.

Llandaff Garden - 30th June

A lovely and warm evening, a balmy 21.2 C. Sadly, it was a disappointing evening except for a second garden record of Small Elephant Hawk moth, and a lovely micro - Chrysoclista linneella. A new record for the garden.

Creigiau Tuesday 25 June

Some micros from the garden moth box on Tuesday night. my tentative IDs are as follows, but I'm not really sure about any of them so would appreciate assistance before I put them on SEWBReCORD.

Hot in Horton

Two traps left overnight in a garden by Horton Cliff produced a very good haul yesterday morning, with ~944 individuals of 126 species, the more interesting including: Plutella xylostella 20, Argyresthia cupressella 1, Argolamprotes micella 3, Lozotaeniodes formosana 1, Delplanqueia dilutella 2, Anerastia lotella 1, Udea ferrugalis 1, Mecyna asinalis 2, Privet Hawk-moth 8, Silky Wave 1, Mullein Wave 2, Small Blood-vein 1, Fern 3, Pretty Chalk Carpet 1, Haworth's Pug 3, Shaded Pug 1, Grass Emerald 6, Reddish Light Arches 2, Shore Wainscot 5, L-album Wainscot 3, Devonshire Wainscot 1, Sand Dart 2 & Crescent Dart 1. With a count 217, Dark Arches was the commonest species, followed by 180 Heart & Darts and 50 Large Yellow ‘Underpants’. 

Later in the day we called in to see Veronica in Cwm Ivy; she had also recorded a bumper catch which including a Vestal she had potted up. She also observed a Hummingbird Hawk in her garden a couple of days previously and I saw one in the middle of Merthyr on the 26th. On the 27th we had two species at home, Argyresthia cupressella and Scarlet Tiger, taking our Gorseinon urban garden list onto 756.

Moths on Dyer's Greenweed

There are quite a few rare micro-moths on Dyer's Greenweed (there's even a Butterfly Conservation factsheet devoted to them, see here).  One of the reasons the moths are rare is that greenweed is a much declined plant of old pastures. Another reason is that management of remaining stands of the plant is often inappropriate for the moths, for example heavy grazing or mowing in late spring or early summer would remove any micro-moth larvae that would be feeding on the plants at the time.

Last year I found a larva of Mirificarma lentiginosella on greenweed on a chance visit to Cosmeston Lakes CP (see blog post here). I followed this up with a survey for Butterfly Conservation at Lavernock Point Nature Reserve last week, and was delighted to find not only quite a few M. lentiginosella larvae, but also four larvae of the rarer Agonopterix atomella. The latter species was only known from around 10 UK sites, with no Welsh records since the 1970s (those were in Gwent, where I failed to find it on surveys in 2014-2015).

Encouraged by this I thought it was worth a more extensive search at Cosmeston, and a visit yesterday resulted in a couple of M. lentiginosella and, more excitingly, seven larvae of A. atomella. These were spread over a wide area, in three different fields.

So we now know of two Welsh sites for these scarce moths, both in Glamorgan and separated by only a mile or two. The moths might be out there somewhere else, but there aren't many sites with good stands of the foodplant.
