Holly Blue Celastrina argiolus
An opportunity not to be missed!
Very unusual to have livestock available: this is the first time ever! These may produce Holly Blue butterflies this summer, or they may hibernate.
The larvae feed inside the flowers and berries of Holly and Ivy. They can be reared on the flowers or pods of Broom and probably other plants of the same family. They live solitarily and are canibalistic, so keep them apart.
These larvae will produce another generation of butterflies this year. The second generation passes the winter in the dormant pupal stage.
