Lawn Grubs Australia including Curl Grub and Army Worm

Lawn Grubs in Australia are commonly named (in the vernacular) when referring to different lawn eating insects.

Lawn GrubsThe different lawn grubs / insects include:

  1. those (like army worm) that forage on the leaves of lawn turf grasses, and
  2. those (like curl grub) that target and feed on the roots of lawn turf grasses and other host plants including ornamental plants

The Lawn Insect Pests that target the lawn grass itself (above the ground) include leaf eating caterpillars such as lawn armyworm and sod web worm. Other pests that may also damage (in different ways) the lawn leaves include couch mite and bill bug (a weevil insect).

Damage to the root systems of plants and lawn turf grasses is mainly caused by Curl Grub (which is the juvenile form of Black Beetle).

Curl Grub (also known as White Curl Grub, cockchafer or scarab beetle larvae) is a larvae of the Black Beetle. The larvae or grub is not a caterpillar (like the army worm) but is the larvae of whatever the scarab beetle is. These scarab beetles include Christmas beetle and Black Beetle.

Curl Grub plague populations (that is, problem infestations) in lawns are evidenced by random patchy damage caused by turf grass root feeding. This damage becomes noticeable in the summer hot dry periods around Christmas (in Australia). The lawn damage is manifested by random dead lawn patches where the dead grass is pulled out easily.

The Before photo was taken in October 2021 and the After photo in January 2022. The damage is really obvious and calls for a heavy duty insecticide treatment program every Spring & Summer regardless of whether the lawn is replaced or not.
