Große Veränderliche Grasbüscheleule

The clouded bordered brindle (Apamea crenata) is a noctuid moth in the family Noctuidae found across temperate Europe and across northern Asia to Japan. The adult wingspan measures approximately 38–45 mm, with intricately patterned grey-brown and buff forewings bearing subtle cross-lines, a scalloped (crenate) outer margin giving the species its name, and distinctive reniform and orbicular markings characteristic of the Apamea genus. Adults fly in one generation from May to July, visiting flowers for nectar at night. The larvae feed internally within the stems and roots of grasses, particularly Brachypodium and other coarse grass species in woodland rides, woodland margins, and rough grassland habitats. Overwintering occurs as a larva within plant stems. Like many grass-feeding noctuids, the clouded bordered brindle requires structural diversity in its grassland and woodland edge habitats, with areas of tall, tussocky grasses providing both larval foodplants and adult shelter. Population trends in parts of its European range reflect changes in land management affecting coarse grassland and woodland ride quality.

Rauhes Hornblatt

<em>Ceratophyllum demersum</em>, commonly known as common coontail or hornwort, is a submerged aquatic plant in the family Ceratophyllaceae. It has an almost cosmopolitan distribution, occurring on every continent except Antarctica in freshwater lakes, ponds, slow-moving rivers, and ditches. Common coontail is rootless, floating freely or loosely anchored in sediment, and forms dense underwater mats that provide important habitat and refuge for fish, invertebrates, and waterfowl. Its whorled, forked leaves are stiff and brittle with toothed margins. The species is well adapted to a wide range of water conditions and can tolerate turbid, nutrient-rich waters where other aquatic plants may struggle. It plays a significant role in aquatic ecosystems by oxygenating water and filtering excess nutrients. The species is assessed as Least Concern by the IUCN. Biological traits of this species remain poorly documented in the scientific literature.
