Polyommatus icarus is a common resident. The species occurs in a variety of flower-rich habitats, irrespective of nutrient level, pH or humidity. Habitats include waste ground, grasslands and roadside verges. Several species of Fabaceae serve as larval foodplant. The species flies in two, sometimes three, generations from mid-May until the end of August, and hibernates as a half-grown caterpillar. Numbers appear to have been stable during the 20th century; data from the Dutch Monitoring Scheme indicate a moderate increase since 1992.
