The Apollo (Parnassius apollo Linné, 1758)
The Apollo is a butterfly of the family Papilionidae. In France, it is mainly found between 1000 and 2000m. Caterpillars overwinter as juvenile in the egg, and hatch in early spring (March). They feed on the leaves of host plants of the family Crassulaceae, mainly white stonecrop (Sedum album). Around May-June the caterpillar spin a loose cocoon slightly buried or placed in the dry grass, in which it pupates. After ten days to several weeks the butterfly emerge. The Apollo flies in one generation from June to August, sometimes September in the highest places. They preferentially gathers nectar from purple flowers.
