Migrants again (2)

Well, that little warm but very windy patch produced no further migrants at all here!  On the 21st I had a Winter Moth and two Satellites, on the 22nd just a Dingy Footman caterpillar, while last night there were two December Moths and singletons of Red-green Carpet, Winter Moth, Feathered Thorn & Scarce Umber.  The 8mm Dingy Footman caterpillar had presumably been tempted out of hibernation and was found climbing one of our conservatory windows beside the actinic light which was being run indoors against the glass.

Your Records!

After a concerted effort over the past couple of weeks I've now entered nearly 17,000 records from 2017 into MapMate and, barring dissections and data from the Marsh Gibbon RIS trap, I'm at last almost up-to-date with inputs.  I therefore now feel comfortable reminding everyone else how vitally important your records are.  If you haven't already done so, you too should now be considering getting them together in whatever form you use to pass on to your County Moth Recorder.

That data doesn't just sit on your CMR's computer (honest!).  It gets passed on to the National Moth Recording Scheme which is managed by Butterfly Conservation and is used to inform conservation activities for moths throughout the UK.

If you haven't contributed records before (or if you've forgotten how to go about doing so), you'll find all the information you need under the "YOUR RECORDS" tab at the top of this page.

Migrants again

We seem to have another small window for immigration with a warmer southerly airflow now and for the next two or three nights.  Last night the actinic light was run inside the conservatory here, bringing ten species to the windows and amongst which were Udea ferrugalis (1) & Silver Y (1) which may have been migrants, although the Silver Y seemed to be on its last legs whereas migrants are usually very fresh-looking.

The other moths comprised Emmelina monodactyla (1), December Moth (1, another female), Common Marbled Carpet (1), Red-green Carpet (1), Winter Moth (6), Feathered Thorn (1), Mottled Umber (1) & Angle Shades (1).  The Common Marbled Carpet was my latest sighting by a week.

Tachystola acroxantha

The trio of moths caught on the night of 15th/16th November included this Ruddy Streak (Tachystola acroxantha).


The other two were Red-line Quaker and Spruce Carpet.

Hebrew Character

I was starting to wonder where the December moths had got to and then caught 17 on Tuesday night along with 9 other species including a very worn Setaceous Hebrew Character. I decided to put the trap out again last night hoping for a Grey Shoulder-knot or a Scarce Umber to add to the 2017 list and was quite surprised to get this Hebrew Character.

Plumed Prominent

Martin Albertini and I trapped speculatively in some mixed woodland near Marlow, Bucks last night in the hope of finding Plumed Prominent at a new site.  Four MV traps were run from dusk (just before 5pm) and it proved to be a successful evening with four males appearing at around about their usual time (between 6pm and 7pm), divided between three of our four lights.  The session added two new tetrads to the known distribution in our area of this Nationally Scarce 'A' list species which only flies at this time of year.

There wasn't much else flying, although it was nice to confirm both Autumnal Moth and Northern Winter Moth amongst those which did appear.

December Eggs

Although rather damp, but because it was distinctly warmer I decided to run the actinic light my usual lazy winter way last night (inside the conservatory and recording what comes to the windows).  Ten moths put in an appearance:  Blastobasis lacticolella (1), Emmelina monodactyla (1), December Moth (3), Red-green Carpet (1), Winter Moth (2), Feathered Thorn (1) & Mottled Umber (1).  One of the Decembers was a female and when I photographed her this morning she wouldn't stop laying eggs.  I'll probably keep them safe until the caterpillars emerge in the spring and then release them locally.

December moth

I too put my trap out on Thursday 9th in the hope of catching another Oak Rustic. Unfortunately one didn't show up but I did catch 26 moths of 7 species. December moth 10, Feathered Thorn 5, Red green carpet 3, Yellow line Quaker 3, November moth 3, Mottled Umber 1 and Brick 1.
I couldn't get over how fluffy the December moth was. Definitely got his winter coat on!
