Black Beetle

The adult black beetle is 14mm long and eats the roots of grass and other plants in summer to mid autumn. All stages of this beetle live predominantly underground, so inspection is advised before spraying with insecticide.
Symptoms
The grass dies in patches for no apparent reason. The lawn has adamaged root system and looks brown or discoloured.
