Cwmllwyd 19 October 2018

Only 40 moths of 14 species were trapped at Cwmllwyd last night (19th October), but some were of interest, along with one that's a bit of a puzzle. Some pix:

 Merveille du Jour

 Red Sword-grass

 Black Rustic - an Autumn favourite of mine,

 The greenest Red-green Carpet I've ever seen!

Could this be Eana osseana? It would be very late, if it is. Flight season (Sterling & Parsons) late June - August, into September and October in Scotland. Seen here once before - August 2016.

Dark Chestnuts

I wonder if anyone else is finding a relative abundance of Dark Chestnuts this year.  I was very surprised to discover that, prior to this year, I have only recorded the species three times in eight years.  Four have turned up this month, including one last night.  These are two of them:

                    9-10-2018                                       19-10-2018

I know that id-ing DC can be tricky so I hope that I've got these right!  Maybe I've been over-cautious in the past and this is responsible for the low counts.

Last night was not good, mostly clear and moonlit, no moths entered the 6w actinic trap but the 22w actinic fared a little better, apart from the DC it contained 2 Green-brindled Crescents, 2 Red-line Quakers, and 1 Yellow-line Quaker.  Fantastic!

Keeping dry...

Usually rain only bothers me if it occurs at inspection time in the morning and I personally get wet. The `electrics` of the trap can be safeguarded by careful wrapping in a bin bag, but sometimes the moths get spoiled by rainwater in the trap.
I`ve had in mind doing some form of shelter for sometime now and, recently, I asked the talented odd-job man/builder/carpenter who I`ve had working weekly on a house for the last two years to make me a couple of shelters for my traps, especially as there was both spare wood and clear corrugated plastic that had been used to make a mini-greenhouse.
The removable plastic top fits snugly onto the folding back and sides, locking the latter into place; the sides and back are open to allow access to the trap by moths and the clear plastic allows light to be seen from above. The trap is positioned with the sloping roof facing the predominant wind/rain direction (normally SW or W in this part of the world).
The only complication was finding a special hinge that allowed the wooden framework to fold absolutely flat for storage.
These covers, which (size-wise)  are suitable for both my actinic and MV traps would have been useful for Storm Callum last weekend, when I mostly missed out on rare migrants due to non-trapping. The lower cross bars of the wooden framework are deliberately set at the very bottom in order to allow `ballasting` in high winds.

Wales Tree of the Year

Not strictly moths so please delete if unsuitable.
Our Rhandirmwyn tree, the Pwllpriddog Oak has won the Woodland Trust, Wales Tree of the Year competition. It is now going for National tree of the year. It is probably 500+ years old, so will have seen more than a few moths in its branches in that time! It must be ecologically important, with all the lichens and invertebrates that still call it home!
If you have time could you please vote for it????
Many thanks.

Hypsopygia glaucinalis

Had this in the trap last night, Hypsopygia glaucinalis, I think I've got the id correct.
Of interest?

Micros in Burry Port

Tachystola acroxantha seems quite firmly established near my garden, so when I found three in the trap I decided to go for an ambitious triple moth shot. Of course they legged it, though I relocated two in the conservatory.

 I also found two Blastobasis lacticolella/decolorella - a bit different from my usual adustella visitors.
And finally a micro I couldn't identify - is it a Crambid? Or Diurnea? I don't know.

Monday Night at Maenol

MV and Actinic traps were used last night and the returns were modest considering the favourable conditions.  59 moths of 22 species turned up, the highlights being second generation Brussels lace, Satellite, FFY Mottled Umber, and a Tortrix which I believe to be Acleris sparsana:

                      Satellite                                     Brussels Lace

                Mottled Umber                               Acleris sparsana

The other species recorded were, in frequency order:  Green-brindled Crescent 10; November Moth agg. 9; Yellow-line Quaker 7; Spruce Carpet 5; Red-line Quaker 4; Feathered Thorn 3; 2 each of Red-green Carpet, Setaceous Hebrew Character, Merveille du Jour, Brown-spot Pinion, Silver Y; singles of Common Marbled Carpet, Black Rustic, Brindled Green, Chestnut, Angle Shades and Pale Mottled Willow.  One Agonopterix sp. (probably A.heracliana, to be confirmed) appeared later (escapee).
