The clouded magpie (Abraxas sylvata) is a geometrid moth in the family Geometridae found across temperate Europe, extending eastward through Russia to Japan. The adult wingspan measures approximately 32–42 mm, with white wings bearing a distinctive pattern of yellow-orange and dark grey to black spots and patches arranged in rows across the forewing and hindwing, creating a striking patterned appearance resembling the magpie coloring of the related magpie moth Abraxas grossulariata, but with a more yellowish, muted tone and less black — hence 'clouded.' Adults fly in one generation from June to July, resting on leaf surfaces and attending woodland flowers for nectar. The larvae feed on wych elm (Ulmus glabra) and occasionally other Ulmus species in mature deciduous woodland and woodland edges. The clouded magpie has become less common in parts of its European range due to the widespread loss of mature elms from Dutch elm disease, which devastated European elm populations from the 1970s onward. Conservation of this species requires the protection of surviving mature elm trees and management of regrowth elms in woodland ecosystems.

<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.
