Plebejus
Blues
Plebejus is a genus of small butterflies in the family Lycaenidae, commonly known as "blues." Species occur in the Palearctic and Nearctic realms. Several species have been observed engaging in mutualistic relationships with ants, where caterpillars produce sugar secretions in exchange for protection. The genus has been subject to taxonomic revision, with several formerly independent genera now tentatively included.
