Habitat & Geographic Range

Chocolate Milky

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and North America (United States). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Cone-headed Grasshopper

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Chocolate Milky

The Chocolate Milky (Lactarius lignyotus) is a medium-sized ectomycorrhizal mushroom in the family Russulaceae, found in coniferous and mixed forests across Europe, North America, and temperate Asia. Like all members of the genus Lactarius, it exudes a milky latex when the flesh is broken — in L. lignyotus, this latex is white and acrid, contributing to the genus's widespread edibility variation. The fruiting body features a distinctive dark chocolate-brown to sooty-brown, velvety cap with a central boss (umbo), similarly coloured gills, and a dark brown stipe, making it relatively recognisable among forest mushrooms. It grows in close association with spruce (Picea) and fir (Abies) trees, forming ectomycorrhizal symbioses in which the fungal mycelium envelopes root tips and exchanges mineral nutrients for plant photosynthates, a relationship fundamental to the health of boreal and montane conifer forests. The IUCN classifies the chocolate milky as Endangered in certain regional assessments, reflecting declines in suitable habitat quality linked to changes in forest management, nitrogen deposition from atmospheric pollution, and climate change affecting the timing and abundance of fruiting. Accurate population monitoring of ectomycorrhizal fungi is challenging given that the fungal organism itself is largely subterranean, visible only when fruiting.

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.
