FLIGHT TIMES AND PREFERRED FOOD PLANTS:
Amorpha juglandis adults fly from May-August in the northern part of their range, and as at least four broods in Louisiana from March-October.
Amorpha juglandis larvae feed upon Walnut and butternut (Juglans), hickory (Carya), alder (Alnus), beech (Fagus), hazelnut (Corylus), and hop-hornbeam (Ostrya).

The moths will often remain "in copula" (paired) until the following evening. The male will fly off in search of another female, and the female will fly off to deposit her green eggs, as many as 200-300 of them (note her swollen abdomen, below).

This is one of the first Sphingidae I reared as a boy.
I fed them on hop-hornbeam in a sleeve by our backyard pond/river in New Jersey. I wasn't ready for them when they reached maturity and didn't know they would pupate in a bucket under loose paper towelling.
Seana Saxon sends these nice images from Dallas, Texas, August 3, 2006. The pointed head (outlined in yellow), grainy skin and dominant last abdominal stripe are diagnostic.

Susie sent me the image of the Amorpha juglandis image posted above. It had been forwarded to her by her daughter for identification, with the actual image taken by Isaac Savage.
Usually Amorpha juglandis larvae are without the red patches, but the red markings can occur to varying degrees. More consistent characters for this species are the raised whitish dots in regular rings around the girth, the pointed head capsule and the two small protuberances, one on the upper outer edge of each anal claspers.
There are seven diagonal lines with the one extending to the anal horn being the most pronounced.
