Holly blue
The holly blue (Celastrina argiolus) is a species in the order butterflies and moths (Lepidoptera), the superfamily Papilionoidea, the family gossamer-winged butterflies (Lycaenidae), the subfamily coppers (Lycaeninae), and the genus Celastrina. The species is widespread in Europe and North Africa.

Adult Celastrina argiolus reach wingspans of 23 - 30 mm. The female’s wings are slightly wider than the male’s. The upper surface of the wings is light blue and has black edges. The black colour on the edges is even more apparent in females of the 2nd generation. The undersides of the wings are whitish-blue with small, black patches and spots.
The holly blue prefers to live in forests and is seen from April to September. It produces 2 new generations a year. The females lay their eggs in holly and ivy, the food plants of their caterpillars, and also on Rubus, currants (Ribes), lupines (Lupinus), vetch (Vicia), Prunus, strawberry trees (Arbutus), common buckthorn (Frangula) and blueberries (Vaccinium). The pupae of the second generation overwinter, and the adult holly blues hatch in April.
