Good autumn fare

An MV here at Cnwc y Llwyn produced 51 species in perfect weather last night.  The abundance of Micros and Geometridae was remarkable - e.g. 15+ Acleris laterana, 7+ A. variegana and 1 A. rhombana.  Two metallic greenish noctuids were very nice:

Brindled Green (left) and Green-brindled Crescent (right).  Other goodies included 3 Pinion-streaked Snout, 4 Peach Blossom, 2 Broad-bordered Yellow Underwing, 2 Frosted Orange, 4 Autumnal Rustic, 4 Black Rustic, 2 Pink-barred Sallow, 1 Hedge Rustic and 1 Copper Underwing.

As we get into autumn I think it gets increasingly difficult for Actinic catches to keep up with MVs, but I'm probably biased.


  1. Glad that you too trapped on Weds night. In the event, I did n`t do a repeat home trap last night (Thurs) as, by the time I got home, it was pitch black and I was too tired.
    You`re still doing the magic `Midas-touch` with the micros, Sam (eg your North-West Frontier blog), and you are welcome to `trespass` in SN40 & SN50! Passports can be arranged! Keep up the good work.

  2. I know that my experience here may not be representative because moth numbers are generally lower than yours at Cnwc, and at some other trapping sites, but Wednesday night's catch was fairly typical: small actinic trap 20 moths, MV trap 12 moths. These were the moths that actually entered the trap, not including those few that remained outside. I tend to find that the MV probably attracts a greater number of moths, but fewer of them end up inside the trap. There are usually more moths on and around the MV in the morning than there are outside the actinic traps.
