Creigiau 29 November

Forecast was good for last night so put the trap out to see what was about. Minimum temperature of 9C with very little wind but only three moths were attracted by the light - Light Brown Apple Moth, Rusty-dot Pearl and my first December Moth of the year.

Overnight in Bridgend 28Nov14

Our optimism in putting the MV trap out last night yielded a nice but worn Feathered Thorn, accompanied by 3 Light Brown Apple moth.

We also found a small micro indoors which with the help of another moth'er seems to be Garden Cosmet / Mompha subbistrigella, our 200th species for the year and our 369th species for the house / garden.

Anyone know what this is?

My industrious 9 year old daughter Holly has found this while rooting around in the bathroom. Given her previous track record with co-finding Welsh firsts, I thought I'd better check this one out. I'm sure I recognise it from the past somewhere (Blastobasis sp?), but can't work out what it is. Perhaps at best 5mm long - I took the liberty of putting the end of a ruler in the photo.

I've just seen the price of the forthcoming MBGBI volumes on the tortricidae:

Hoping they'll do paperback in the future!

Grey Shoulder-knot?

Have just rescued this from an old cobweb hanging outside the patio doors. Looks like a Grey Shoulder-knot to me but I have never seen one before so would welcome a confirmation.



Creigiau 22 November

Also had 2 Rusty-dot Pearl in/on the trap on Saturday night, along with 2 Red-green Carpet and a Light Brown apple Moth. First moths for ages!

Sunday 23 November 2014


Still some migrant activity with 4 Rusty-dot Pearl (U. ferrugalis) on the windows this am.

Wednesday 19 November 2014


Still some moth activity including migrants, had Silver Y, Feathered Thorn, Common Plume (E. monodactyla) & Rusty-dot Pearl (U. ferrugalis) at Whitchurch Hosp. 16th & 18th Nov.
Also a Red Admiral 15th Nov. @ Lakeside.

One from the summer

I never got chance to post this at the time, but way back on 28th May I found lots of large Coleophora cases, and associated leaf mines, on Wych Elm growing at Llandaff Weir, Cardiff. The cases appeared much too large for C. serratella and looked a good match for C. limosipennella - the ID was confirmed by John Langmaid from photos.

This is the first confirmed record of this species in VC41. There was a 1930s record made by Cox at Taff's Well, but this was rejected by the GMRG committee as the case was on birch, whereas limosipennella feeds only on elm.

The cases were abundant and the mines very obvious, so worth looking out for this species elsewhere in Glamorgan next year. They are considerably larger than the similar-looking serratella cases which can also be found on elm.

Llandaff North last night

With warm (and very wet) southerlies returning last night, I stuck the trap out more in hope than expectation. There was a migrant in the trap this morning, but just a Rusty-dot Pearl. It had a crippled forewing and I don't think it could have flown very far, so probably a locally bred specimen (I reared through a larva of this species found on Sea Beat at Barry Island last year, so they definitely breed locally). The only other moths in the trap were White-shouldered House-moth and Light Brown Apple Moth.

Also a RDP on a shop window in Swansea today.

Death's-head Hawk at KNNR

The first record in VC41 since Sept. 2007 (Roath, Cardiff) and the 60th record overall for Glamorgan. The best (influx) years being: 1933 with 7 recs & 4 recs in 2003. Now all we need is the name of the finder!

Death's-Head Hawk

I see there was one at Kenfig yesterday - still worth trapping then...

Phyllonorycter junoniella at Craig y Llyn

In early October, Barry Stewart, Sam Bosanquet and I came across some leaf mines on Cowberry while on a bryophyte excursion to Craig y Llyn (the NPT bit of the crag). I took a couple home and puzzled over them for a while, and initially misidentified them as Ectoedemia weaveri. Fortunately, John Langmaid wasn't convinced and eventually the mine was correctly identified as an early stage Phyllonorycter junoniella mine, the ID being helped by a dead larva extracted from one of the mines.

Phyllonorycter junoniella mine on Cowberry

The species is already on the VC41 list, but the only record is from way back in 1926 (F. Norton) and is from Welsh St Donat's on the Vale coast - a long long way from any Cowberry. Dave provided the following information about this early record:

"Norton's records come from Hallett's annotated fauna of Glamorgan, and it is possible that there may have been a specimen but it's not one that Jake & I looked for during the research stage.

That said, looking at the record in Hallett's list, it does look to say "Lithocolletis racoiniella Scott" - which we obviously misread as Lithocolletis vacciniella (Stainton). There is no name in Kloet and Hinks, and as far as I can tell the only Lithocolletis that Scott described is irradiella (now lautella). Indeed there is a mis-translation on tinternet that reads vacciniella as racciniella - but Hallett wasn't using ORS software to work out his species names, and it is unlike him to get spelling and authority wrong, so a real mystery."

So, not officially a first county record, but probably the first genuine record.

Migrant reaches Llanishen shock...

Actually caught a decent migrant over the weekend, a Small Mottled Willow, only the second I've had in Llanishen.

Gowerton Saturday

Certainly can't compete with Paul but I did have a nice Vestal this morning; a migrant, judging by the colour. Also did see a second P vitrealis at Whitford yesterday morning.
