Chuck-will's-widow

The Chuck-will's-widow (Antrostomus carolinensis) is the largest nightjar in North America, named for its distinctive far-carrying call — a resonant four-syllable whistle repeated persistently on warm nights. It breeds across the southeastern United States, from the Atlantic coastal plain through the Gulf states and up the Mississippi Valley to southern Indiana and Kansas. The species migrates southward in autumn to winter quarters in the Caribbean, Central America, and northern South America. Like all nightjars, it is a crepuscular and nocturnal insectivore, capturing large moths, beetles, and other flying insects in flight using its enormous, bristle-fringed gape. By day, the Chuck-will's-widow roosts on the ground or along horizontal branches, relying on cryptic mottled plumage for concealment. It nests directly on the leaf litter of open woodland and scrub, typically in pine-oak forests, dry forests, and woodland edges. The IUCN classifies this species as Least Concern, though Breeding Bird Survey data suggest moderate long-term population declines linked to forest fragmentation and light pollution that disrupts insect prey availability. Conservation of large-scale woodland tracts in the southeastern United States benefits this species and its associated nightjar community.

Cocksfoot Moth

The cocksfoot moth (Glyphipterix simpliciella) is a tiny moth in the family Glyphipterigidae with a wingspan of only 6–8 millimetres, native to temperate grasslands and meadows across much of Europe, including Belgium, Denmark, Norway, and Sweden, as well as parts of Asia. Adults are attractively marked with silver and orange-brown scales on the forewings, making them conspicuous despite their small size when they fly in the sunshine of meadows and grassy areas from May to July. The species is closely associated with cocksfoot grass (Dactylis glomerata), the larval food plant after which it is named. Females lay eggs in the spikelets of cocksfoot and other grasses; larvae develop within the seed heads, feeding on the developing seeds, before pupating in the grass tussock. Adults are diurnal, basking and flying on warm days and often observed resting on grass stems with wings held roof-like over the body. Glyphipterix simpliciella is widespread in grassland habitats from lowland meadows to upland pastures and is one of the more frequently encountered members of its family across its European range. It is classified as Least Concern by the IUCN, with stable populations supported by the wide distribution of its grass hosts across managed and semi-natural grasslands. The species is considered a useful bioindicator of species-rich traditional grasslands in parts of its range.
