Holly Blue (Celastrina argiolus): This pretty butterfly emerges in April after pupating over winter. This generation lays eggs on the base of holly flowers, where the pupae feed on the developing flowers and berries. They emerge as adults in July and August, when the female, distinguished by a black margins of the upper front wings, lays her eggs on the developing ivy flowers, which the larvae consume. Since the cemetery is full of holly and ivy, it is no surprise that this site is one of the best in Cambridgeshire, and is generally the first place to record their emergence in spring.
