A migrant plume at Merthyr Mawr

Paul and I trapped at Merthyr Mawr last night, hoping for an early Portland Moth (no luck on that front). I did a bit of dusking while waiting for darkness to fall, and netted a small plume that I almost dismissed as Adaina microdactyla before I'd had a proper look at it. Luckily I potted it and Colin Hart has now confirmed it as Crombrugghia laetus, a scarce migrant and the first record for Glamorgan.

There was a mini influx of these back in 2011 and I was lucky enough to see one in North Wales. Barry thought he had one at Nitten around the same time, but was without a pot when he saw it and so it was never confirmed. It's nice to get it on the county list at last!

Cardiff docklands

I drove around a few sites near Cardiff Docks before the rain this morning. The Purple Toadflax plants at Tremorfa Industrial Estate, which held two Toadflax Brocade larvae in 2015, had five larvae on them today.
At Pengam Moors, a very large (for a micro) larva of Depressaria radiella was on Wild Parsnip flowers.
Nearby on the Rhymney saltmarsh I found an occupied mine of Chrysoesthia sexguttella on orache (Atriplex sp) - the 4th VC record and first for Cardiff.

Dunraven dusking.

Creigiau last week

Had two quite good boxes in the garden last week, 49 species on Friday (14 July) and 56 species on Tuesday (18 July) - across the two nights 18 species made their first visit of the year. Highlights included the first ever visits by Anania crocealis, Clay and Narrow-winged Pug.

Always some queries ... is this one a faded Gypsonoma dealbana?

and these two are causing me some grief. The first (from Friday) I thought may be Common Rustic but then I had, what looked like, a definite Common Rustic on Tuesday. They are both very similar in size at approx 15m - so what is the first one? I thought it could possibly be Small Clouded Brindle, but I'm not convinced bby that either. Assistance gratefully received.

Cadoxton Ponds

I trapped at the Dow Corning site that we manage (Cadoxton Ponds) on tuesday night despite the forecast of thunderstorms and I'm glad we did as I had a few moths that were new to me and at least a couple that are uncommon in Glamorgan I believe. Over 340 moths of 100 species in total with over 30 newly recorded for the site (it's only the 8th time I've trapped).
Highlights for me were dusky sallow, Monochroa palustrellus, Epiblema foenella, the crescent, Coleophora trifolii (about 8mm in length and noticeably bigger than another metallic Coleophora caught), vapourer, ghost moth (female), garden tiger and diamond-back moth amongst many other lovely moths. Most frequent were smoky wainscot (35) and lackey (18). Apologies for the quality of all the photographs - my excuse(s) are very poor light, strong wind and tiredness...
Dusky sallow
Monochroa palustrellus

A few I would like help with please:
1. Batia lunaris?

2. Blastobasis lacticolella?

3. Elachista sp.

4. Gypsonoma dealbana?

5. square-spot rustic?

6. Not sure

7. faded wormwood pug?

Rhymney Estuary

I left two battery-powered traps out on the saltmarsh at Pengam Moors on Tuesday night - the last warm night before the weather cooled off. The traps were tucked out of sight of roads and footpaths - the kind of trapping Ian Morgan specialises in (see Carms blog).

There was nothing massively exciting among the macro-moths, though Round-winged Muslin is new for the Glamorgan bit of ST27 I think.

The micros did include some saltmarsh specialists - there were 9 Gynnidomorpha vectisana in one trap, as well as 30+ Coleophora and a few Scrobipalpa (the latter two will need dissecting to confirm ID).
Gynnidomorpha vectisana


MCP & myself went down last night to Llanbethery with the intention of trapping Lunar-spotted Pinion, a species we have caught there before. However most of the elms there have died & we were unfortunately unsuccessful. On a brighter note we did trap just over 80 species. Eight were new for ST06. The highlights were Satin Lutestring, Grass Emerald, The Mocha, Beautiful Carpet, Browntail, Double Lobed & The Crescent. Thanks to DJS for some ID.

Bridgend 17th July

A lovely warm night produced a catch of 103 moths of 48 species. The highlight for us was a new one for the garden Swammerdamia pyrella. Also new for the year were Apple Ermine (agg), Bactra lancealana and Ancylis badiana (last recorded 2013), Mompha propinquella, Barred Fruit-tree Tortrix, Phoenix, July Highflyer, August Thorn, Poplar Hawkmoth, Dingy Footman, Garden Tiger, Lesser Broad-bordered Yellow Underwing, Knot-grass, Dotted Clay (2013) and Marbled Green.

This takes the garden year list to a very good 151 (97 macro / 54 micro). The garden list now stands at 417 (272/145).
