Catocala unijuga
I collected 2 Catocala in Wrangell the 8th and 9th of September, 2013, both attracted to our porch lite (I'll be posting their photos shortly). It created alot of interest amongst lepidopterists since they were the first records of the genus for Alaska. Both were mailed to Larry Gall in Connecticut for id confirmation. They were 2 different species. According to Larry and others, the median black band on the hind wing extending all the way to the inner edge makes this C. unijuga. On C. semirelicta this band doesn't make it to the inner margin. I'll let Larry and the others know about this record as well. Do you know if the moth was collected?

No, it wasn't collected, unfortunately. The person who saw it just figured it was something pretty normal. I did send a note to Cliff Ferris who was the lead author on the recently published checklist of the moths of Alaska - he mentioned that others in the genus had been reported this year as well in south coastal Alaska, but he didn't mention where.

On a separate note, I don't know if you've seen it before, but I've been working on a Natural History wiki for Southeast Alaska. I've been compiling species lists from various resources as I've had the time (though there is still a lot to go, especially in the realm of invertebrates). I did enter most of the butterflies and moths that have been reported from Southeast so far:
Southeast Alaska Lepidoptera, the moths based on the state checklist, and the butterflies based on what I found on the maps of e-Fauna BC. Since I started paying more attention to moths, there have been several found in Sitka that were not previously known from the region (or even state, in some cases) - most of which I've added to the wiki. I would love to have more information/photos from the Wrangell area included if you're interested in helping to contribute.


positive id not possible
According to Larry Gall, positive id of Catocala's can't be made from photos, he has to have the specimen. So the unijuga id is unconfirmable.

It's most likely C. unijuga
Bob Borth, one of the lepidopterists working on the Catocala revision, is pretty certain that this is a photo of C. unijuga.
