In termites, primary reproductives proceed through dispersal flight with finite metabolic
reserves. During colony foundation, the mated pair requires just enough resources to …

Trade‐offs between life‐history traits–such as fecundity and survival–have been
demonstrated in several studies. In eusocial insects, the number of organisms and their …

In social animals, body size can be shaped by multiple factors, such as direct genetic effects,
maternal effects, or the social environment. In ants, the body size of queens correlates with …

Bumblebees and other eusocial bees offer a unique opportunity to analyze the evolution of
body size differences between sexes. The workers, being sterile females, are not subject to …

Social insect colonies are pinnacles of evolved altruism but also exhibit dramatic conflict
among relatives [1, 2]. In many species, a colony's workers compete with the queen and …

Little is known about the roles of sex pheromones in mate‐finding behavior of social wasps
(V espidae). Working with the aerial yellowjacket, D olichovespula arenaria (F abricius) …

Many species exhibit distinct phenotypic classes, such as sexes in dioecious species or
castes in social species. The evolution of these classes is affected by the genetic …

Highly social species are successful because they cooperate in obligately integrated
societies. We examined temporal genetic variation in the eusocial wasp Vespula …

Many social species show variation in their social structure in response to different
environmental conditions. For example, colonies of the yellowjacket wasp Vespula …

Females of many species are polyandrous. However, polyandry can give rise to conflict
among individuals within families. We examined the level of polyandry and paternity skew in …
