Cyclocephala borealis

Also known as Northern Masked Chafer Beetle, Northern White Grub

Northern masked chafers are nocturnal scarab beetles recognized by the dark brown mask-like markings across their heads and eyes. Adults emerge from lawn and pasture soils during warm summer evenings, flying toward porch lights while foregoing feeding entirely during their brief adult lives. Below ground, their white grub larvae feed voraciously on grass roots, making them prominent turfgrass pests across North America.
