Out and about

The adults hide out in winter in sheltered spots and come out in the spring to lay eggs. Most species are tropical or subtropical. Coreidae bugs are widespread throughout Australia.

Reproduction and Life cycle

Females lay a loose cluster of about 18 eggs on the underside of leaves. In warmer regions there may be two generations in a season. The eggs, which are an orange-brown colour, take 7 to 9 days to hatch. The nymphs go through 5 stages (instars) over about 1 month.

Why they are a Pest
As with all pod suckers they pierce and suck the pods of plants such as beans as well as the developing fruits of plants such as cucumbers, stone fruit, citrus and grapes. They attack the pod when it is young and soft then, as the pod hardens it becomes dry and misshapen. Fruit will either become badly blemished or drop off before it develops. They will also attack the new shoots of plants causing them to wither and death in young plants. They can also transmit diseases from plant to plant.
