Our understanding of bee phylogeny has improved over the past fifteen years as a result of
new data, primarily nucleotide sequence data, and new methods, primarily model-based …

Division of labour—individuals specializing in different activities—features prominently in the
spectacular success of the social insects. Until recently, genetic and genomic analyses of …

Sweat bees have repeatedly gained and lost eusociality, a transition from individual to group
reproduction. Here we generate chromosome-length genome assemblies for 17 species …

Revision of the metallic Lasioglossum (Dialictus) of eastern North America (Hymenoptera:
Halictidae: Halictini) Page 1 Accepted by E. Almeida: 12 Sep. 2011; published: 28 Oct. 2011 …

The evolution of eusociality in Hymenoptera—encompassing bees, ants, and wasps—is
characterized by multiple gains and losses of social living, making this group a prime model …

We report the draft genome sequence of the red harvester ant, Pogonomyrmex barbatus.
The genome was sequenced using 454 pyrosequencing, and the current assembly and …

A long-standing controversy in bee social evolution concerns whether highly eusocial
behavior has evolved once or twice within the corbiculate Apidae. Corbiculate bees include …

Eusociality has arisen independently at least 11 times in insects. Despite this convergence,
there are striking differences among eusocial lifestyles, ranging from species living in small …

The halictid bees are excellent models for the study of social evolution because greater
social diversity and plasticity are observed in the tribe Halictini than in any other comparable …

I redevelop the hypothesis that lifetime monogamy is a fundamental condition for the
evolution of eusocial lineages with permanent non-reproductive castes, and that later …
