Sphenophorus venatus venatus
hunting billbug
Sphenophorus venatus venatus is a subspecies of hunting billbug, a weevil in the family Dryophthoridae. It is widely distributed across North America and has been documented in Middle America, Spain, and Corsica. This subspecies is associated with grass habitats, particularly Cynodon dactylon (bermudagrass), and exhibits chemically-mediated host and mate recognition behaviors. Males are attracted to host-plant volatiles and conspecific cues, while females respond to male conspecifics. The species uses both volatile and contact chemical cues for orientation and recognition.
