Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (8 countries), Europe (12 countries), and North America (Canada, United States).

Fly Agaric

Habitat

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

Clover weevil

The clover weevil (Sitona hispidulus) is a small herbivorous beetle in the family Curculionidae, subfamily Entiminae. Native to the Palearctic region across Europe and Asia, this species has been introduced to North America, where it is now widespread across agricultural regions. Adults and larvae feed on clovers and other legumes in the genus Trifolium and related plants. Adults feed on the leaves, creating characteristic semicircular notches along leaf margins, a feeding pattern typical of Sitona weevils. Larvae feed underground on nitrogen-fixing root nodules, which can reduce the agronomic value of legume crops by damaging the symbiotic Rhizobium bacteria. The clover weevil is consequently regarded as an agricultural pest in clover-growing regions. Adults are grey-brown and densely covered in scales, measuring about 3–5 mm in length. The species overwinters as adults in soil or leaf litter, emerging in spring to feed and reproduce. It inhabits cultivated fields, pastures, meadows, roadsides, and any habitat supporting clover and related legumes. Listed as Least Concern by the IUCN given its wide distribution and abundance.

Fly Agaric

Among the most iconic and recognizable fungi on Earth, fly agaric mushrooms display striking red caps with white flecked warts across boreal forests of the Northern Hemisphere. Despite their fairy-tale appearance, they contain potent psychoactive compounds including muscimol and ibotenic acid and are moderately toxic. They form critical mycorrhizal symbioses with birch, pine, and spruce trees, exchanging mineral nutrients for carbon and playing essential roles in boreal forest nutrient cycling.
