Behavior Patterns

They are primarily nocturnal or crepuscular, often burying themselves in the soil during the day. Their life cycle involves a one-year generation where they overwinter as grubs.

Risks & Benefits

They are considered a significant ornamental and turf pest. The larval stage can damage lawns and nursery stock by eating root systems. They pose no direct risk to humans.
