Nestmate Copulation in the Neotropical Eusocial Wasp Polistes Instabilis de Saussure (Hymenoptera: Vespidae) by Sean O'Donnell

“…Copulation between individually marked nestmates of the Neotropical eusocial wasp Polistes instabilis is reported. Polistes copulations are rarely observed in the field; this observation is the first documented case of nestmate copulation in the genus. …”

The Effects of the Social Hierarchy Destabilization on the Foraging Activity of Eusocial Wasp Mischocyttarus cerberus styx Richards, 1940 (Hymenoptera: Vespidae: Polistinae) by Vanderlei Conceição Costa Filho, Sulene Noriko Shima, Ivan Cesar Desuó, André Sunao Nishiuchi Murakami

“…The genus Mischocyttarus comprises 245 species of neotropical basal eusocial wasps. They form small colonies (rarely more than few tens of individuals); castes are morphologically undifferentiated and determined behaviorally by agonistic interactions. …”

The impact of social complexity on the efficacy of natural selection in termites by Roux, Camille, Ha, Alice, Weyna, Arthur, Lode, Morgan, Romiguier, Jonathan

“…In eusocial species, reproduction is monopolized by a few reproductive individuals.From the perspective of population genetics, this implies that the effective population size (Ne) of these organisms is likely to be smaller compared to solitary species, as has been proposed in the literature for eusocial hymenoptera. …”

The multifaceted role of brood communication in wasp societies by Rafael Carvalho da Silva, Fabio Santos do Nascimento, Cintia Akemi Oi

“…The family Vespidae represents a key group to understand the evolutionary trajectory of social behavior in insects, as these wasps display the entire spectrum of social behaviors, from solitary to highly eusocial. The evolution of eusociality likely depended on a coordinated communication system, with chemical communication being suggested as the most commonly used among social insects. …”
