Habitat & Geographic Range

Clover Melitta

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Luxembourg, Norway, and Sweden. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Common corncockle

Habitat

Found across multiple habitat types including montane grasslands and shrublands, tropical and subtropical moist broadleaf forests, and temperate coniferous forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Lesotho), Asia (7 countries), Europe (24 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (Brazil, Chile). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Clover Melitta

The clover Melitta (Melitta leporina) is a solitary bee in the family Melittidae, order Hymenoptera, with a distribution centered on temperate Europe including Belgium, Denmark, Luxembourg, Norway, and Sweden. Unlike social bees, Melitta species are ground-nesting solitary bees in which each female constructs and provisions her own nest independently. M. leporina is oligolectic — highly specialized in its pollen collection — gathering pollen almost exclusively from leguminous plants, particularly clovers (Trifolium), alfalfa (Medicago sativa), and related species in the family Fabaceae. This specialization makes the bee closely dependent on the availability of flowering legume patches within foraging distance of nesting sites. Nest sites are in bare or sparsely vegetated sandy or loamy soils, often in sunny, sheltered locations such as road embankments, field margins, and sandy grasslands. Adults fly from midsummer through early autumn in a single annual generation. M. leporina is classified as Near Threatened on the IUCN Red List, reflecting declining populations across much of its European range due to agricultural intensification, loss of flower-rich grasslands, reduction in diverse legume cultivation, and loss of suitable open nesting habitat. Conservation of M. leporina depends on maintaining semi-natural grassland habitats with diverse flowering legumes and accessible sandy soils for nesting, along with reduction of pesticide use that harms adult foraging and larval survival.

Common corncockle

<em>Agrostemma githago</em>, commonly known as common corncockle, is an annual flowering plant in the family Caryophyllaceae. Once a widespread weed of cereal crops across Europe, Asia, and beyond, this species is now Critically Endangered on the IUCN Red List due to the dramatic decline caused by modern agricultural practices, particularly improved grain cleaning and herbicide use. Corncockle is a tall, slender plant covered in silky white hairs, bearing large, solitary pink to purple flowers with distinctive dark veining. Its seeds contain toxic saponin compounds called githagins, which historically contaminated grain supplies. The species now survives primarily in wildflower conservation areas, seed banks, and traditional farmland conservation schemes. It typically grows in open, disturbed arable soils with full sun exposure. Biological traits of this species remain poorly documented in the scientific literature.
