* Lemaire indicates neither A. b. bilinea nor A. b. tamphilus for Paraguay. His stated ranges, however, indicate A. b. tamphilus with a more southerly range in Brazil so I have tentatively identified the specimen from Guaira (above) as A. b. tamphilus. Ulf Drechsel also has A. bilinea listed for Concepcion Department in Paraguay, and I believe that is more likely the nominate subspecies. The difference seems more a slight variation in colour as there are no consistent differences in genitalia. Lemaire indicates tamphilus generally has a chrome coloured fw terminal area in sharper contrast to the more uniform baso-median area, and in that regard the specimen depicted above is more like the nominate subspecies.
In Europe, Bernhard Wenczel reports Salix sp. (willow), Rosacaeae (rose, cherry), and Fagaceae (beech, oak, chestnut) are used with great success.

Males are able to locate the females by tracking the airbourne pheromone with their highly developed antennae.
This species mates readily in captivity. Peak activity occurs from 10:30 pm until shortly after midnight.
