Chocolateweed

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical coniferous forests, and tropical and subtropical dry broadleaf forests. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (4 countries), Asia (4 countries), North America (United States), and Oceania and the Pacific (Fiji, Micronesia, Solomon Islands).

Common Yellow Conch

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, 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.

Common Yellow Conch

<em>Agapeta hamana</em>, the common yellow conch moth, is a small moth in the family Tortricidae. It is widely distributed across Europe and central Asia, ranging from Britain and Scandinavia eastward through much of the Palearctic region. The species inhabits dry grasslands, heathlands, chalk downlands, and scrubby habitats where its larval host plants are found. Adult moths display distinctive pale yellow to golden-yellow forewings with irregular brown or reddish-brown markings near the wingtip, forming a pattern that resembles the shell of a conch, lending the species its common name. The wingspan typically measures around 15–22 mm. Biological traits such as average adult lifespan, precise body weight, and detailed population data remain poorly documented in consolidated scientific literature. Larvae feed internally on the roots of thistles and knapweeds, particularly <em>Centaurea</em> and <em>Cirsium</em> species. Adults fly from June to August and are frequently attracted to light. <em>Agapeta hamana</em> has been investigated as a potential biological control agent for invasive knapweed species in North America, where it has been introduced experimentally. The species is assessed as Least Concern given its broad distribution and stable habitat associations.
