Maenol Moth Nights 1 & 2

Thursday night produced a reasonable catch from an MV/actinic combination, current tally 104 moths of 31 species.  Brimstone was the most abundant by far, 24 of them.  Notable were Pinion-streaked Snout and a Caryocolum sp., looks to be the same as the one I had on August 20 (currently with Dave Slade for gen. det.), although yesterday's is not as well marked.

I'm still puzzling over one noctuid, perhaps someone would be kind enough to help me.  I'm probably being blind to the obvious, but its narrow shape doesn't suggest a Square-spot Rustic, more Chestnut-like, and the intricate pattern of black scales is confusing, it's the one on the left in the photo:

Last night was far too wet to put a trap out, there's nowhere here sufficiently sheltered from such heavy rain, but I left the porch light on and this morning 5 Brimstones, 2 Flounced Rustics, 1 Angle Shades, 1 Pink-barred Sallow and a 20 Plume Moth had braved the conditions.  It's fine just now, if it remains so I will use an actinic trap tonight.


  1. I think that is a Square-spot Rustic, Chris. The Caryocolum looks interesting.

  2. I thought S-spR was the most likely outcome Sam, but the shape and black speckled appearance made me question it. Regarding the Caryocolum, if Dave can show that the first one's C. blandella, isn't it reasonable to assume that the latest one's the same? As far as I can tell from available sources C.blandulella is the only alternative with the same features, and it's very unlikely to be found here.

    1. What makes you say Caryocolum blandulella is unlikely? Jon has had it in Carms after all. I'll try to dissect the one I've got this weekend.
