Gastrimargus marmoratus, commonly referred to as the Bandwing Grasshopper, is known for its striking appearance and the characteristic sound it produces during flight, which is created by the rapid movement of its wings. These grasshoppers have prominent hind wings that are often brightly colored with bands, which are visible when they fly, serving as a deterrent to predators.

Other Information
Venomous?
Bandwing Grasshoppers do not possess any poison and are harmless in terms of chemical defenses.
A Danger to Humans?
There is no direct danger to humans from Bandwing Grasshoppers. They do not bite or sting. However, like other grasshoppers, they can be a pest in agricultural areas due to their feeding habits.
Population Status
Specific data on the population size of Gastrimargus marmoratus is not extensively documented, but they are not considered endangered or under significant threat in most of their range.
Life Span:
The life span of Bandwing Grasshoppers is relatively short, typically lasting one year or less. Their life cycle includes stages as an egg, nymph, and adult.
Weight and Length:
These grasshoppers, being larger than many other species, can weigh significantly more, especially in their adult stage. Adults of this species can range from 40 to 65 mm in length, making them quite conspicuous.
Distribution:
Gastrimargus marmoratus is primarily found in Australia, particularly thriving in grasslands, open woodlands, and farmland across the continent.
Habits and Lifestyle:
These grasshoppers are highly active during the day (diurnal). They are known for their ability to jump long distances and fly with a buzzing sound, especially when threatened or disturbed. This mobility helps them escape from predators and disperse across wide areas.
Diet and Nutrition:
Bandwing Grasshoppers are primarily herbivorous, feeding on a variety of grasses and occasionally broad-leaved plants. They are especially known for consuming and sometimes damaging crops, which can classify them as agricultural pests in certain regions.
Mating Habits:
The mating behavior of Bandwing Grasshoppers involves males attracting females through their distinctive flying noises and display of their colorful wings. Females lay eggs in the soil, which will hatch into nymphs that undergo several molting stages before reaching maturity. The cycle is highly dependent on seasonal conditions, with reproduction typically peaking in warmer months.
