clouded magpie

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.

Common Hawkweed

Common hawkweed, <em>Hieracium vulgatum</em>, is a flowering plant belonging to the family Asteraceae. This species is distributed across Belgium and Norway, reflecting a range within northern and western Europe. As a member of the large and taxonomically complex genus Hieracium, <em>Hieracium vulgatum</em> is a perennial herbaceous plant typically found in open habitats such as grasslands, woodland margins, rocky slopes, and disturbed areas. The genus is characterized by its yellow composite flower heads and is known for extreme taxonomic diversity, in part due to widespread apomixis. The species typically grows in relatively dry to moderately moist soils. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
