Résumé :	Not all floral visitors attracted to flowers are pollinators Instead, some visitors circumvent the floral opening, usually removing nectar without contacting the anthers and/or stigma Here we review the evolutionary ecology of nectar robbing from both the plant and animal perspective Effects of robbing on female and male components of plant reproduction range from negative to positive Their underlying mechanisms are diverse, including direct effects and indirect effects mediated through changes in pollination We detail how plants may be able to deter robbers through morphological and chemical traits For the evolutionary ecology of robbing to move beyond a phytocentric perspective, studies must also address the causes of robbing and the consequences for both robbers and pollinators We use an energetics approach to evaluate these causes and consequences Finally, we highlight unanswered questions in need of further research
