Habitat & Geographic Range

Common Flat-body

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Common Yew

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, tundra, and tropical and subtropical moist broadleaf forests, among 6 distinct biome types spanning the Australasia and Oceanian and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Libya), Europe (10 countries), North America (United States), Oceania and the Pacific (New Zealand), and South America (Brazil). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Flat-body

<em>Agonopterix heracliana</em> is a moth belonging to the family Depressariidae within the order Lepidoptera. Commonly known as the common flat-body, this species is named for the flattened resting posture characteristic of the genus Agonopterix. The species is classified as Least Concern on the IUCN Red List, with no indication of significant population decline. <em>Agonopterix heracliana</em> is distributed across northwestern Europe, with documented occurrences in Belgium, Denmark, Norway, and Sweden. Larvae of this species are typically associated with plants in the family Apiaceae, particularly hogweed (Heracleum sphondylium) and related umbellifers, upon which they feed while sheltering in rolled or folded leaves. Adults are typically brownish with subtle markings and are active from late summer through winter and early spring, overwintering as adults — an unusual life history trait among moths. The species inhabits hedgerows, woodland margins, and meadows where its host plants are abundant. Biological traits of this species remain poorly documented in the scientific literature.

Common Yew

<em>Taxus baccata</em>, the common yew or English yew, is a slow-growing evergreen conifer in the family Taxaceae, native to western, central, and southern Europe, northwest Africa, and southwest Asia. It is one of the longest-lived trees in the Northern Hemisphere, with some individuals estimated to be several thousand years old. The species grows in a variety of habitats including mixed deciduous woodland, calcareous scrub, chalk downlands, and rocky slopes, often as an understorey or emergent tree. Yews are dioecious; female trees produce distinctive bright red fleshy arils surrounding a single hard seed, the only non-toxic part of the plant. All other parts, including the leaves, bark, and seeds, contain highly toxic taxine alkaloids that are dangerous to humans and most animals. Average lifespan can exceed 1,000 years under suitable conditions. <em>Taxus baccata</em> is ecologically important as dense, long-lived woodland habitat and as food for birds that disperse its seeds. Medicinally, taxol derived from yew bark is used in cancer treatment. The species is assessed as Vulnerable due to habitat degradation, overgrazing, and historic overexploitation across parts of its native range, though it remains locally common.
