Overview
Callophrys avis, the Chapman's green hairstreak is a small butterfly found in the Palearctic that belongs to the blues family. The males and females of this little butterfly are identical. The underside of the wings is green, the upperside is greyish brown. The green verso is marked by a mediodiscal white line that differentiates this species from Callophrys rubi. The larva feeds on Coriaria myrtifolia, Arbutus unedo, Salvia verbenaca, Viburnum tinus.
Chapman's Green Hairstreak faces significant threats from habitat loss and degradation due to agricultural expansion and urban development across its range. Climate change poses additional risks by altering the distribution and phenology of its host plants, while habitat fragmentation isolates populations and reduces genetic diversity.
Habitat
Inhabits scrubland, heathland, chalk downs, and woodland edges with abundant buckthorn and other Rhamnus species that serve as larval host plants. Typically found in areas with short grassland and scattered shrubs at elevations up to 600 meters.
