Australian alpine grasshopper

insect
Also known as: Kosciuscola tristis

Quick Summary

The Australian alpine grasshopper (Kosciuscola tristis) is an insect belonging to the order Orthoptera. This species exhibits a remarkable temperature-dependent color change. Adult males are bright greenish-blue above 25°C (77°F) and turn dull blackish below 15°C (59°F), with intermediate shades at intermediate temperatures. This color change is controlled by the migration of brown and blue granules within the grasshopper's epidermal cells.1

Grasshoppers, in general, are known for their jumping ability due to enlarged hind legs and are found in various habitats worldwide. They undergo simple metamorphosis, with life stages including egg, nymph, and adult. While most grasshoppers are herbivorous, some species can be significant agricultural pests.23
