A Crazy Month

December 2015 has been an exceptional month. Usually I only trap on favourable nights in Winter. So if its too cold or too windy, I've tended not to bother. Unfortunately, I haven't got 'blanks' recorded for the first years of my records. A bit of a blunder really, though as said, this wouldn't account for many if any nights in some years, so not as scientific as I would have liked. But I suppose you can get the gist of it.
Clearly the high yields are down to high temperatures at night. This has led to more than a few surprises up and down the country, especially on the South coast. December isn't usually considered to be a highlight in migrant terms. But the season hasn't really tailed off since October. I for one will keep the traps burning until the end of the year as anything seems possible.

Black-spotted Chestnut
 This was the surprise of the year, caught 18th Decmber. Though I missed out on getting my first 'New for VC' macro moth by a matter of 20 hours as one was caught in Biggleswade (17th December)- by my father!
Incredibly, this species has only been know in the UK since 2011 and I actually had to renew my Mapmate licence to update my checklist as it didn't exist!
The only other records come from a small colony in Kent and a single record in Suffolk. Easily the rarest moth I've ever caught and the furthest North the species has ever been recorded in Britain!

Spring Usher
 .........Though should be called the 'Christmas Usher' this year. After an early record from The Lodge, Sandy on 17th, I was still very surprised to catch this on 21st December. My previous earliest record was 18th January!
Scarce Umber
Fairly scarce in my garden, usually with one record per year. All previous record have been in November. But this turned up 7th December.

Below is all of my records from the garden in December. This year comes off the back of three blanks, so makes it particularly unusual.
