Comparison of moth catches

As promised in the previous post, I have been comparing the catch from one of last nights traps with that from the same trap in the same place on 6/12/16. I realise that this is completely unscientific and no conclusions can be drawn. The fewer species and smaller numbers could be due to weather conditions, although last night was quite mild and still. Note in diary to trap same place same time next year.

More December Moths

A few from last night in woodland.  This does not compare favourably to a similar time and the same location last year.  Tony will do the analysis later but in the mean time a few photos.

December Moths

We had 42 moths of six species in our oak woodland trap last night despite hail showers and a minimum temperature of 0.9°C.  These included one female and four male December Moths.  There was a size difference of 7 mm and the respective antennae are clearly visible in this photo.  The other moths comprised Winter Moth, Chestnut, Red-green Carpet, Grey Shoulder-knot & 32 Mottled Umber.

Cross Inn 21Nov

Put the trap out on a warm misty night and got no adult moths.

I did however get this...any ideas for ident? I did think that the slightly smudgy markings might prove distinctive.

Mottled Umber and Dark Chestnut

Encouraged by Tony's haul on Thursday I put the trap out last night, under an umbrella. Only four moths, these two and a couple of Chestnuts. It was the first outing this month

A few more migrants - Silver Y and Rusty-dot Pearl

I gave the garden trap one more go last night, before the cold nights are back for a bit.  This time I had 28 moths of 12 species.  Amongst the usual autumn moths was a Common Marbled Carpet (very worn), a Psychoides filicivora, 1 Silver Y and 3 x Rusty-dot Pearl.

The winter moths are here

With the promise of a mild night we were tempted to run 3 traps at Ynys-hir last night. We recorded over 160 moths with 14 macros and 1 micro, Rusty-dot Pearl (2). Most numerous were November Moth agg., Feathered Thorn, Mottled Umber, December Moth (22 of them). Also in the mix were Chestnut, Grey Pine Carpet, Red-green Carpet, Yellow-line Quaker, Red-line Quaker, Satellite, Green-brindled Crescent, Winter Moth, Northern Winter Moth, and Pale Brindled Beauty.
The Pale Brindled Beauty is the earliest ever county record by almost 2 weeks, another indication of climate change?
