Black, White, and Gray Moth with Close-Spaced Wavy Lines

2014 October 18

Here’s another medium-sized porch light moth from September 8, 2013

Given that it doesn’t have the kidney-shaped “reniform spot” that is common in most of the owlet moths, it is most likely something else. The best match I’ve found (it even has the right pattern of dark spots on its white feet), is the “Once-Married Underwing”[1], Catocala unijuga

I’m sorry I wasn’t able to get a picture of the hindwings. Checking back in my notes, I see that when it flew off I saw that it had bright red-orange hindwings with a black stripe acros them. Unfortunately, it didn’t settle down and give me a chance to catch it, so you’ll just have to take my word for it.

[1] There doesn’t seem to be any particular significance to the common name “Once-Married”. BugGuide just says that the names for the various underwings “are often fanciful and arbitrary”.

    Are you sure that wasn’t just a piece of ash from your Weber grill?
