COAM in the rain...

I left a light at the COAM site on a timer last night. Everything was very wet this morning, but there were lots of moths, so worthwhile I guess.

I've managed to id 83 species; new for the year were Oegoconia quadripuncta agg., Aethes rubigana, Pleuroptya ruralis (Mother of Pearl), Hypsopygia costalis (Gold Triangle),  Single-dotted Wave, Dingy Footman, Buff Footman, Dot Moth, Brown-line Bright-eye and Grey Dagger agg., but here are a few micros I'd appreciate some help on...

 (4) - Batis lunaris, or any chance it could be internella??

(1) and (5) look like they may be the same sp. to me?

  1. Now, see that first picture Dave? It must be the most requested micro ID at this time of year and it has made one or two appearances on the blog already. I know the colours can vary in their intensity but the wing shape is always a dead giveaway - it is Rhopobota naevana. Numbers two and five are both Ancylis achatana, which is another common moth at this time of year and one worth remembering. The third is a Spilonota, probably ocellana but the image isn't really sufficiently clear to rule out laricana if you have larch nearby. I expect the Batia will be lunaris but if you want to make it into one of the larger species then save it for Peter!

  2. Thanx Dave!
    It's always useful to have pointers as to why something is what it is, so the Holly Tortrix wingshape...
    The Ancylis is actually a new one for me.
    The Spilonota, there is no larch in "line of sight" from where the trap was, or particularly nearby, but I'll have to "agg" it I guess (it was rather worn and I don't have it).
    The Batia may have to visit Peter. I'm sure it is the common one, but you never know...maybe because the book says internella is "perhaps overlooked". Size-wise it is right on the cusp.
