Cyclocephala lunulata
masked chafer
Cyclocephala lunulata is a rhinoceros beetle in the family Scarabaeidae, widely distributed across the Americas from the southwestern United States through Mexico and Central America to South America. Adults are attracted to volatile organic compounds produced by bacteria (VOCsB) isolated from their genital chambers, with both sexes responding to bacterial volatiles from Morganella morganii. The species is a documented agricultural pest of strawberry, guava, and ornamental pastures.
