I also had a Red Data Book 2 Longhorn beetle Pyrrhidium sanguineum today, which the Longhorn group is quite pleased with!
White-marked

A Carmarthenshire First
A good night for my trap last night. Amongst the Common and Small Quakers were two slightly different moths. The first was a White-marked and the second a Blossom Underwing. Dafydd Davies caught the Blossom Underwing regularly here in Rhandirmwyn, but Sam says this is the first verified record.

Well done Jane. Your record helps to show that the vast majority of Rothamstead records from Carms are really good data. In the absence of verified recent records Blossom Underwing was pended, but Dafydd Davies' records are spot-on for dates and numbers and are very clearly correct. They have all been upgraded, as is the usual process with pended records (as opposed to obvious ID errors, which are marked as rejected).
ReplyDeleteThe only other thing to consider is whether Jane's moth was a migrant, given southerly winds and records of 'migrant' Blossom Underwing in England. My only Dingestow records come from good migrant years, so I am unsure whether the species is resident in my bit of VC35. I would guess from Dafydd's records that Blossom Underwing is resident at Rhandirmwyn , but it would be good to scrutinise the data.
If you get a chance, please put a photo of the longhorn on the blog too (even though it`s a beetle). There is a record from Parc Dinefwr (Llandeilo) and possibly from Cilycwm (will check the latter tomorrow).
ReplyDeleteWell done Jane.
The only other known Carms record of this longhorn is indeed at Dinefwr and not Cilycwm (the latter referred to Prionus coriarus, another rarity that you caught last August). Pyrrhidium is confined to mid-Wales and the southern Welsh borderland, a curious distribution of which I have some thoughts...perhaps reflecting post-glacial colonisation via major river systems that drain into the S Irish sea/Bristol Channel.
ReplyDeleteOn another matter and as an aside, I looked for orange underwings yesterday afternoon (at a known site, Cencoed-uchaf) and failed, though I only spent c 15 mins or so.
Pyrrhidium is a gorgeous beetle, and one that I hope to refind here at Dingestow (VC35) this year. I saw it 4 times in 2006/07 when there was a big pile of oak logs in the parkland, but haven't since. It's odd that it uses parkland Pedunculate Oak and old woodland Sessile Oak.
