My first ever ID request, after years using the site (thank you): I think this is one of the Prominent Moths - Schizura species, but I can't find an ID. (I can say those are my 4 yr old daughter's bitten fingernails!) It came onto the porch of our cottage--kids found it. It was hard to photograph: would not stop moving, fast, so this is a still from an iPhone video, slightly sharpened using an editor. The most striking features to me were the smooth body with what I think of (imprecisely!) as "heterocampa" type blotches, the head, which was whiter than it appears here, and the horn, which was large, red, and a bit strange - at first I thought it was an erupting parasite! Thanks in advance for help!
