Common catchfly

<em>Silene gallica</em>, commonly known as the common catchfly, is a plant species that was historically distributed across Africa, Asia, Europe, the Americas, and Oceania. It typically occupied diverse terrestrial habitats, often found in disturbed ground, arable fields, roadsides, and sandy or rocky soils in temperate and Mediterranean regions. The species is classified as Extinct on the IUCN Red List, indicating that it is no longer known to exist in the wild. Common catchfly belongs to the genus <em>Silene</em> within the family Caryophyllaceae and was a slender annual herb notable for its small, often pink or white flowers and sticky stems. The loss of this species is attributed to habitat degradation, agricultural intensification, and the reduction of traditional farming practices that once maintained the open, disturbed habitats it depended upon. Biological traits such as average lifespan, plant height, and mass of this species remain poorly documented in the scientific literature. Its extinction represents a permanent loss of biodiversity across its formerly wide global range.

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.
