Description
The Holly Blue (Celastrina argiolus) is a small, vibrant blue butterfly found across the Palearctic region. It is known for its two broods, with the first often associated with Holly and the second with Ivy, giving it its common name. The underside of its wings is a pale silvery-blue or white, lacking the spots common in many other 'blue' butterflies.
