Coleophora virgaureae

To continue the recent Coleophora case theme, I found three cases of C. virgaureae while mapping Marsh Fritillary habitat along a forestry ride near Bryn, Neath Port Talbot yesterday. Cases were on the seedheads of goldenrod. MBGBI vol. 3 says the cases are hidden in the seedheads but two of the three were clearly visible without having to pick the seedheads apart (see circled case in photo below).

The larva makes a silken case to which it attaches fine hairs from the seedheads.


As far as I know there are just two previous county records, both from the 1920s, but given that I found it on the first plant I looked at it is likely to be very under-recorded. Timing is important - the larva only makes a case in its final instar, so there is probably only a brief window of opportunity in which the cases can be found.

Mallow at Whiteford

This time last week I arranged to go to Whiteford as the weather forecast looked good; warm, cloudy, humid.
It would have been a bit late for Mallow but might have been a chance. In the event the sky cleared and there was a fullish moon and it got very cold very quickly, total catch 3 moths: Silver Y, Autumnal Rustic, Pine Carpet.
However, Veronica in Cwm Ivy gave me hot chocolate and a chance to photograph one she had caught earlier, so not a total waste.

Cypress Carpet in Bridgend

Another small catch overnight in the garden, but the highlights were Cypress Carpet and Blair's Shoulder-knot (both pictured) and Large Ranunculus.

Bridgend, night of 10th October

Out went the MV trap into the garden again and we were lucky to get a nice selection: 2 LB Apple moth, 3 CM Carpet, 1 Barred Sallow (first here since 2007), 1 Black Rustic, 1 Angle Shades and a Silver Y. Year list has reached 156 (109 macro) pretty poor compared to recent years.

Parc Slip

Only 15 moths of 9 species in the trap last night but it was worth setting for a new macro - my first ever barred sallow (it was on the site species list but without a date or recorder name). Also my first merveille du jours of the year, a smart black rustic, a couple of ab. capucina green-brindled crescents and my first November moth agg. of the year. Also a couple of micros in the form of a diamond-back and a light brown apple moth.

Coleophora violacea

Another nice Coleophora case in the Alun Valley. This C. violacea was spotted feeding on blackthorn during a site meeting on Monday. I think there is just one previous VC41 record, from Taff's Well in 1939.

Long-tailed Blue in Llantwit

I've just had a report of a Long-tailed Blue from Llantwit Major on the 3rd October. I don't think there are any photos, but you never know! Dave
