elk

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and temperate broadleaf and mixed forests, among 12 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (South Africa), Asia (Afghanistan, Indonesia), Europe (11 countries), North America (Mexico), Oceania and the Pacific (Australia, New Zealand), and South America (Argentina, Chile, Peru). 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.

elk

Also known as the red deer, elk are among the largest members of the deer family, with antlered males reaching up to 240 kg. Found across temperate forests and grasslands of Europe, Asia, and North America, where populations were historically separated as distinct subspecies. Males shed and regrow their antlers annually, engaging in dramatic roaring contests during autumn rut. An important game and conservation species across its range.
