Adult Hedge Grasshopper (Valanga irregularis)
During January to March, populations of Hedge Grasshoppers are almost entirely nymphs, which mature by about April. They pass winter in the adult stage, mate in early summer, and females lay eggs in pods in the ground. Midsummer rains trigger the eggs to hatch.
Adults and nymphs usually feed on broad-leaved shrubs, such as acalypha and hibiscus, but also damage palms. This is a common and conspicuous grasshopper in coastal south-east Queensland that thrives in well-watered suburban gardens. It occurs in open forest close to the coast, from northern Western Australia, the Northern Territory and Queensland to northern New South Wales.
