I believe in spiracles


Giant grasshopper (Valanga irregularis) are the largest grasshoppers in Australia.

Notice the spines on their hind legs, if they are caught by birds or by spider web, they will attack their predators by their hind legs.

A spiracle is surrounded by an annular sclerite, called peritreme. It also has a valve wich regulate the opening and closure of the spiracle with the help of certain sphincter/spiracular muscles. This helps to regulate the flow of air and prevents the loss of moisture from the body.

Insects and some more derived spiders have spiracles on their exoskeletons to allow air to enter the trachea. In the respiratory system of insects, the tracheal tubes primarily deliver oxygen directly into the animals’ tissues.

They have large compound eyes and will see you meters away. If you approach near to them, they try to hide behind the leaf or branches, but will still peep at you by either one of their large eyes. And one oceli.

The adults grasshoppers hibernate during the winter

The black bands on the hind femur and the black spines on the hind legs are identification features.

Grasshoppers have 10 pairs of spiracles, making a total of 20. Eight of these pairs are located along the abdomen, while two are thoracic. Spiracles are part of the respiratory, or tracheal, system of the grasshopper.

Grasshoppers have six legs. They also have two antennae and two pairs of wings.

Air enters the grasshopper’s body through the front spiracles and exits through the rear.

Grasshoppers have clear blood and a tube-like heart.
