Arizona’s Jewel Scarabs emerge after the onset of summer rains. These large insects have something of a cult following among collectors, and enthusiasts from around the world descend on the Sonoran desert every monsoon season with their mercury vapor lamps and blacklights to entice the lumbering beetles into their traps. The effects of this mass harvesting on Chrysina populations have not been studied, but they should be. I’d hate to lose such an attractive species.
Beyer’s scarab, the largest Chrysina in the United States, feeds on oak foliage.
