Ulmen-Fleckenspanner

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.

Steinadler

Among the most powerful and widely distributed raptors in the world, golden eagles have wingspans reaching 2.2 meters and inhabit mountainous terrain across the Northern Hemisphere. Supreme aerial hunters, they use soaring flight and steep dives at speeds over 200 km/h to capture rabbits, hares, ground squirrels, and occasionally young deer and foxes. In many cultures they have been central to falconry traditions spanning millennia.
