Overview

Pseudophilotes bavius, the Bavius blue, is a butterfly of the family Lycaenidae. It is found in Morocco, Algeria, Bulgaria, Romania, Greece, Asia Minor, southern Russia and northern Kazakhstan. The species occurs in small isolated populations on flower-rich, dry grassland, on dry, stony slopes and on open patches in shrub and in vineyards on calcareous soil.

The Bavius Blue butterfly faces severe population declines primarily due to habitat loss and degradation of its specialized Mediterranean scrubland ecosystems. Agricultural intensification, urban development, and changes in traditional land management practices have fragmented and destroyed the specific host plant communities this species depends on for reproduction.
