Habitat & Geographic Range

Common Cone-headed Grasshopper

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Common Frillwort

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and Mediterranean forests and woodlands spanning the Indomalayan and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Found across Asia (Taiwan) and Europe (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Cone-headed Grasshopper

<em>Acrida ungarica</em>, commonly known as the common cone-headed grasshopper, is a large grasshopper in the family Acrididae. This species is notable for its distinctively elongated, conical head that gives it a slender, streamlined appearance. It typically inhabits open grasslands, meadows, scrublands, and the margins of wetlands, where tall grasses provide both food and cover. <em>Acrida ungarica</em> is a phytophagous species that feeds primarily on grasses and other herbaceous plants. Its coloration varies from green to brownish-yellow, offering effective camouflage in its grassy habitat. The species is distributed across parts of Europe and western Asia. It is assessed as Least Concern on the IUCN Red List, with no major threats identified to its populations. Biological traits of this species remain poorly documented in the scientific literature.

Common Frillwort

<em>Fossombronia pusilla</em>, commonly known as the common frillwort, is a small liverwort belonging to the family Fossombroniaceae within the division Marchantiophyta. This non-vascular bryophyte typically grows in moist, disturbed soils, clay banks, and damp pathways across its range in Europe and parts of Asia. The thallus is typically lobed and frilly in appearance, giving the species its common name. <em>Fossombronia pusilla</em> favors habitats with high moisture and reduced competition, often colonizing bare or sparsely vegetated ground following disturbance. Its geographic range spans temperate regions of western and central Europe into Asia, though populations have become increasingly fragmented. The species is currently assessed as Critically Endangered on the IUCN Red List, reflecting severe population declines likely driven by habitat loss, land drainage, and agricultural intensification. Biological traits such as lifespan, body size, and diet remain poorly documented for this species, as is common among many small bryophyte taxa. Like other liverworts, <em>Fossombronia pusilla</em> reproduces both sexually through spores and vegetatively. Conservation of this species depends on protecting moist, low-competition microhabitats and reducing disturbance to its specialized substrates.
