This Arizona State record (above) for 2004 was listed in the Lep Society Season Summary. It was captured in Santa Cruz County, Arizona on the evening of August 7, 2004. Coincidentally it was the first capture of that evening. It came to a combination of Mercury Vapor and Blacklight Fluorescent lights on a hill top in an area with a tremendous amount of Hopbush (Dodonaea viscosa) and Ocotillo.

FLIGHT TIMES:

Dolbogene hartwegii adults fly in August and possibly/probably in other months.

ECLOSION:

Pupae probably wiggle to surface from subterranean chambers just prior to eclosion.

SCENTING AND MATING:

Females call in the males with a pheromone released from a gland at the tip of the abdomen.
