Habitat & Geographic Range

Common Mountain Bush-cricket

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Common Quaking Grass

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate grasslands and steppes, and flooded grasslands and savannas, among 6 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Japan), Europe (7 countries), North America (Canada, United States), and South America (Argentina). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Mountain Bush-cricket

The Common Mountain Bush-cricket (<em>Antaxius pedestris</em>) is an insect in the genus <em>Antaxius</em>, belonging to the family Tettigoniidae within the order Orthoptera. This species is classified as Least Concern on the IUCN Red List, suggesting its populations are currently stable. It is typically found across virtually all terrestrial and freshwater habitats within its range. As a bush-cricket, <em>Antaxius pedestris</em> belongs to a group characterized by long antennae, typically exceeding body length, and the ability to produce sound through stridulation — rubbing the wings together. Bush-crickets are generally omnivorous, feeding on plant material, small invertebrates, and occasionally other insects. The "mountain" designation in its common name reflects an association with elevated, rocky or montane habitats, which are typical for members of this genus in Europe. Detailed biological traits such as average lifespan, body dimensions, and weight are not widely documented for this species in available records. Further taxonomic and ecological research may better define the full distribution and habitat preferences of this species.

Common Quaking Grass

The Common Quaking Grass, <em>Briza media</em>, is a perennial grass in the family Poaceae, native to Europe and parts of Asia and introduced to North America and South America. It is a characteristic species of ancient, species-rich calcareous grasslands, meadows, and chalk downlands, where it typically grows in well-drained, nutrient-poor soils in full sun. The species is easily recognized by its heart-shaped, flattened spikelets that hang on delicate, hair-like stalks and tremble in the slightest breeze, producing the distinctive quaking motion that gives the genus its common name. The spikelets are typically pale green when immature, turning golden-brown as they ripen, and the whole inflorescence is highly ornamental. <em>Briza media</em> is an important component of calcareous grassland communities, providing structure and seed resources for invertebrates and birds. It is sensitive to agricultural improvement and is often used as an indicator of long-undisturbed grasslands. The species is assessed as Vulnerable on the IUCN Red List, reflecting declines linked to habitat loss, agricultural intensification, and conversion of traditional grasslands. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
