I think this is a Green Cloverworm Moth (
Hypena scabra) that came to the back porchlight last weekend. It seems to be a fairly common species, but this is the first one I have seen. Adults fly for most of the year, and larvae feed on a variety of plants, such as alfalfa, beans, clover, ragweed, raspberries, and strawberries.
Like other moths in its genus, it has a distinctive snout-like shape.
