Climbing False Buckwheat

Climbing False Buckwheat, Fallopia scandens (also known as Polygonum scandens), is a vigorous annual or short-lived perennial vine in the family Polygonaceae native to eastern North America, occurring from the Great Plains east to the Atlantic coast and from southern Canada south through the eastern United States to Mexico. It climbs over shrubs, fences, and tall herbs by twining its stems, reaching several meters in length. The leaves are broadly heart-shaped, and the small, greenish-white flowers are borne in elongated, drooping racemes in summer and autumn. The triangular achene fruits are enclosed by winged, pinkish-white tepals that facilitate wind and water dispersal. Climbing False Buckwheat grows in moist, disturbed habitats including stream banks, woodland margins, thickets, roadsides, and fencerows, tolerating a wide range of soil conditions. It is closely related to the invasive Japanese Knotweed (Fallopia japonica) but is less aggressive and is considered native in eastern North America. The seeds are eaten by many birds and small mammals. The species is not threatened and is a common component of disturbed vegetation across its extensive native range.

clouded-bordered brindle

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.
