Polyommatus amandus, Azuré de la jarosse

This butterfly flies from May to August. The larvae feed on species of vetch, often Meadow vetchling (Lathyrus pratensis) and tufted vetch (Vicia cracca). The males fly around near the hostplants waiting for femalesto arrive. The females lay their eggs singly on the leaves of the host plant. The caterpillars have glands which secrete a sugary fluid that attracts ants and the presence of these protects the larvae from predators.
