Grass grubs and beetle

Adult grass grub beetles (Costelytra zealandica) fly in swarms in summer, and eat the leaves of crops and trees. Females lay eggs in moist soil. Underground, the larvae hatch and go through a series of growth stages lasting several months. They then pupate for 4–6 weeks, and emerge as adult beetles in spring and summer.
