Blackthorn Mining Bee

The Blackthorn Mining Bee (Andrena varians) is a species in the genus Andrena. It is currently classified as Least Concern on the IUCN Red List. Distributed across Denmark, Luxembourg, Norway, and Sweden.

Chocolateweed

Chocolateweed (Melochia corchorifolia) is a pantropical annual or short-lived perennial herb in the family Malvaceae, widespread across tropical and subtropical Asia, Africa, the Pacific islands, and Australia. It is a common weed of disturbed and agricultural habitats including rice paddies, riverbanks, roadsides, and field margins, tolerating a wide range of soil types including waterlogged and saline conditions. The plant grows to 40–100 centimetres, producing alternate, toothed leaves and small pink to purplish flowers followed by rounded, ribbed capsule fruits. The stem fibres of Melochia corchorifolia are used traditionally in parts of Asia and Africa as a substitute for jute in making rope, matting, and rough textiles, reflecting the plant's membership in the mallow family which includes many fibre-producing species. The seeds and young leaves are edible in some cultures and the plant has uses in traditional medicine. Despite its status as an agricultural weed, it also provides nectar for bees and other insects. The IUCN classifies it as Least Concern, reflecting its widespread and abundant distribution across tropical agricultural landscapes worldwide. Its success as a coloniser of disturbed habitats suggests high resilience to anthropogenic change.
