It was a dark and stormy night


And warm, too, at a sweltering 50° F, so I made plans to be up late looking for moths and caddisflies. I turned on the porch light, made a little cup of espresso, and waited awhile. When I went out I almost couldn’t believe what I saw: Ancylis albacostana. The broad white band on the forewings certainly seemed to point to that species. But there were some differences. First, the wings are not uniformly leaden gray. Instead, there is a very noticeable amount of red forming a narrow triangle above the white band and is separated from that by a narrow black line. Then, below the white band is a narrow ash gray band. The main part of the forewings are leaden-gray. Finally, near the beginning of the forewings are two raised bumps. When I compared this moth to available photos it seemed not match well at all. The description of Ancylis albacostana by Kearfott is also at odds with this moth’s appearance. In an earlier post (here) I stated I had found Ancylis albacostana but later retracted that (there) when it appeared the moth in question was actually Capis curvata.

Also attracted to the light last night were five individuals of the caddisfly Glyphopsyche irrorata and three of the moth Agonopterix argillacea. I’ll be up late again tonight to get more photos of this Ancylis and other moths.
