The Drosophila repleta group encompasses an ensemble of species that inhabit desertic areas unfriendly to other drosophilids. These species have a tractable ecology since they breed and feed on necrotic tissues of Cactaceae making them suitable models to investigate the role of host plant shifts in diversification. Most species have their own primary host plant that may be shared with a closely related species. However, the consequences of host plant shifts from primary to secondary hosts have not been thoroughfully studied so far.
