Mt. Buffalo Skyhopper

This flightless grasshopper belongs to the genus Kosciuscola, a group of alpine and subalpine acridids known for their distinctive thermal colour-change ability, shifting between dark and lighter hues as temperature fluctuates to regulate body heat. Like its relatives, it is likely a ground-dwelling herbivore, feeding on native grasses and low vegetation, and plays a role in high-elevation food webs as prey for birds and other insectivorous species. Its short wings and reliance on cool, montane conditions reflect an evolutionary specialisation to Australia's alpine and subalpine environments.

The species is restricted to the Mt. Buffalo region of Victoria, Australia, occupying forest, shrubland, and grassland habitats at elevation. This narrow geographic range makes it inherently vulnerable to localised environmental change, as there is little scope for range shifts or population redundancy elsewhere.

The species is classified as Critically Endangered, with a decreasing population trend. Key threats include invasive non-native species and diseases, which may alter habitat structure or introduce novel pressures, as well as introduced genetic material that could affect the integrity of local populations. Habitat shifting and alteration, likely linked to climate-driven changes in alpine vegetation zones, further reduce suitable habitat.

Altered fire regimes and fire suppression practices also affect the grassland and shrubland mosaics the species depends on.

Conservation attention for restricted-range alpine invertebrates in Australia typically involves habitat monitoring, control of invasive species, and management of fire regimes within protected areas such as national parks. Specific population-level interventions for this species are not well documented in available records.

Given its extremely limited range, ongoing habitat pressures, and ecological sensitivity to climate-linked change, the species' outlook remains poor, with continued population decline expected absent significant intervention.
