As a bit of context: Bees and wasps are in the taxonomic order <i>Hymenoptera</i>, which they also share with ants. It is the only order of insects [0] besides <i>Isoptera</i> (termites) with complex social systems and division of labor.<p>Ants, of course, also have a division of labor and, if I understand the terminology, a 'social system'. I wonder if every family/genus/species in <i>Hymenoptera</i> has these capabilities, including learning complex behavior.<p>[0] I'm not sure if precisely, those are the only such orders among insects (class <i>Insecta</i>) or among all arthropods (phylum <i>Arthropoda</i>).
