Llandaff North trapping this week

I've not done a huge amount of garden trapping this summer, but I made a bit more effort this week and trapped on 4 consecutive nights from 5th to 8th August. Wednesday night (7th August) was the most productive with 46 species - not a huge total, but it was notable for the number of interesting noctuids in the catch. Best of the bunch was Southern Wainscot; there are only two previous records of this species from Cardiff, both from the Bay. Mine might have wandered from there, or it may be breeding more locally on Reed Canary-grass on the Taff riverbank or on Common Reed at Forest Farm.
Also of note were Campion (2nd garden record), Bordered Sallow (3rd record), Least Yellow Underwing (1st since 2008) and Dark Sword-grass. The latter might be a relatively common migrant but it's very good at avoiding my garden - this was my first since 2011. Also a Gold Spot and a couple of Euzophera pinguis, which has had a good year here.

On 5th August there was a wandering Catoptria margaritella (3rd garden record of this boggy moorland species) and the pine-feeding Ocnerostoma friesei (approx. 8th county record), and on the exceptionally warm and wet night of 8th August another Least Yellow Underwing.

All in all, a pretty good week.

Barry, 24th July

A couple more NFG and totally new for us, Box-tree moth from the fence by the trap plus Dusky Sallow & Endotricha flammealis both also NFG. Jersey Tigers continue to appear about one or two a night.


A Royal Mantle was caught by Chris Brewer just round the corner from me last night.  Plenty in my trap but nothing this good! Looks like he had a couple of Suspected too.  One in my garden also.

Llandaff - Garden - 23rd July

A very hot and humid evening with thunderstorms. I was unable to run the trap for much longer than midnight due to huge hailstones.

A few micros to check but I did have this wonderful looking beast of a froghopper - Ledra aurita. A local species with only a few records as far as I can see. He has to be around 1.5cm - 2 cm.

Acleris umbrana, Barry, 21st July

Acleris umbrana appears to have made it back into the county... This was found on the side of the trap and my micro blindness initially put it down as something Acleris hastiana-esque until Ben Sale on the micro forum suggested umbrana which seemed to fit.

Checking on the website though I saw only the one record in 1907! But there it was, scale tufts and all.

Also nice to see slap bang on the middle of the trap rain cover after the thunderstorm this morning one of two of the first Jersey Tigers this year:

Llandaff Garden - 21st July

I took this in the trap last night. I'm a tad unsure if it's a Confused, a Nutmeg, Dusky Brocade or other. I'm opting for a Nutmeg.

The wing markings are different with the orbicular stigma elongated on the left and small and oval on the right. I'm sure it's not a rare occurance but a first for me.

Look forward to some input if possible for species ID.

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.

Port Eynon Pug

Visiting for a week from Bucks and trapping in my mum's garden.

This pug came on Saturday night, and as I'm useless at most pugs, someone has suggested Maple Pug (albeit a bit early). I would appreciate the thoughts of those who know better the status locally. I see from the excellent glamorganmoths website (I wish we had similar in Bucks!) that there is a record from Gower in June 2018 so that makes me think it can be early!

Creigiau 06 June

Found this tortrix in Friday night's moth box. I think it could be Cnephasia asseclana, which would be a new moth for me. Grateful for confirmation/correction.

(Don't know why, but I seem unable to reply or comment on this blog at the moment. So apologies to Stephen - I have tried several times to respond to his comment on my 'longhorn' on 22 May)

Stephensia brunnichella

This rather lovely little moth was caught by Elaine Wright at Merthyr-mawr on Saturday. She nearly didn't bother to show it to me thinking it was too tricky. Glad she did, since Stephensia brunnichella has only been recorded three times in Glamorgan, and not since the 1980s!

A rubbish photo as it wouldn't sit still and sadly expired during the course of the afternoon:

Afraid I've got out of the habit of mothing for a couple of years due to other demands on my time. However I saw this Yellow Belle {Aspitates ochrearia} at Cosmeston in the W. paddock yesterday. Never seen one there before but I assume it's not particularly unusual as the habitat is OK acc to UK moths. Thanks to Mike Cram and Paul Parsons for confirming ID for me on Facebook.

Creigiau 19 May

Spotted this 'longhorn' moth when filling the bird feeders in the garden.  I think it could be Nematopogon swammerdamella.

Only ever seen one 'longhorn' before and that was on the Coast Path at Baglan on a 'bee walk' with Liam Olds last summer. That was Adela croesella so this one will be new for me … whatever it is.
Grateful for correction/confirmation.

Llandaff - Garden - 20th May

It's been a rather slow start to the year with very few moths in the trap. The temps were good last night with some decent cloud cover but still no more thatn 20 moths in the trap.

I've a few large pots filled with Purple Toadflax around the garden with the hope of some more Toadflax Brocades appearing. I was in luck as one was in the trap this morning along with a Poplar Hawk, Light Emerald, White-pinion Spotted and usual Heart and Dart etc. Great to see that the Brocades are still around.

New Website

As some of you will know I have been working on a new website for the group. I figure now is as good a time as any to let it out for general consumption! The main purpose of the site is to let people see the records and maps for the species found in Glamorgan, and will be populated with photos, some of which have been collated by me from this blog and it's predecessor, others are new (and thanks to Chris in particular for many of these).

If you want to contribute or have news or events you think should be added then please let me know. I have no desire to be the sole Admin for the site so if you think you can help keep it relevant and up to date then please get in touch.

The new site can be found at enjoy, and let me know if you spot any problems!

Bilberry Pug larva

Last night's Blue Ground Beetle hunt with BugLife at Pontneddfechan failed to produce any Blue Ground Beetles, but in compensation it was nice to find a larva of Bilberry Pug in a spinning on Bilberry. This was close to the footbridge near the Nedd-Pyrddin confluence, but luckily on the VC41 side of the river.

There are 18 VC41 records in my MapMate, all from NPT and Swansea, and all of which are adult records. So perhaps this is the first larval record for Glamorgan?

Highlight Park, Barry

We had a Maiden's Blush to the trap last night. New for this garden and I think first we've ever had.
