Common Glider

<em>Neptis sappho</em>, commonly known as the common glider, is a butterfly in the family Nymphalidae. The species has a broad European distribution, with documented occurrences in 19 countries across the continent. <em>Neptis sappho</em> typically inhabits woodland edges, clearings, and scrubby areas where its larval host plants, primarily species of legumes such as <em>Lathyrus</em> and <em>Vicia</em>, are available. The species is assessed as Least Concern, reflecting its reasonably wide distribution across temperate and sub-Mediterranean Europe. The common glider is named for its characteristic flight pattern, which involves alternating periods of gliding and flapping, producing a distinctive sailing motion through woodland habitats. Its wings are dark brown with white bands and spots that create a striking pattern visible during flight. Biological traits of this species remain poorly documented in the scientific literature. The species typically produces one or two generations per year depending on latitude and climate, and adults are often observed nectaring at flowers in sunny woodland clearings and along forest margins.

Great Reed Warbler

Great Reed Warbler (Acrocephalus arundinaceus) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
