The larval foodplants are various members of the Fabaceae. They include various vetches (Vicia spp), Clovers (Trifolium spp), Medicks (Medicago spp) and most commonly Bird's-foot-trefoil (Lotus corniculatus).

Common Blues overwinter in their half-grown larval state. The pale green caterpillar have yellow stripes; they produce a honeydew-like liquid on which ants feed. To protect their food suppliers the ants in turn ward off predators that might otherwise eat the caterpillars.
