June Bug (specifically a Masked Chafer)

Natural Habitat

Found in lawns, gardens, and agricultural fields; adults are often attracted to bright artificial lights at night.

Diet & Feeding

Adults typically do not feed or feed very little on foliage; larvae (white grubs) feed on the roots of grasses and decaying organic matter.

Behavior Patterns

Nocturnal insects that are clumsy fliers; they often bump into walls and windows while attracted to light. Their life cycle involves subterranean larval stages followed by emergence in early summer.

Risks & Benefits

Harmless to humans as they do not bite or sting. However, the larvae can be significant garden pests by damaging turfgrass roots, while adults provide a food source for birds and small mammals.
