Transcriptome analyses of primitively eusocial wasps reveal novel insights into the evolution of sociality and the origin of alternative phenotypes
These genomic resources for aculeate wasps and first transcriptome-wide insights into the origin of castes bring us closer to a more general understanding of eusocial evolution and how phenotypic diversity arises from the same genome. Expand
Worker caste polymorphism has a genetic basis in Acromyrmex leaf-cutting ants
It is shown that worker caste development in the leaf-cutting ant Acromyrmex echinatior has a significant genetic component, suggesting that a significant role of genetics may have been overlooked in the understanding of other complex polymorphisms of social insects. Expand
Molecular signatures of plastic phenotypes in two eusocial insect species with simple societies
Significance In eusocial insect societies, such as ants and some bees and wasps, phenotypes are highly plastic, generating alternative phenotypes (queens and workers) from the same genome. TheExpand
The genomes of two key bumblebee species with primitive eusocial organization
Overall, gene repertoires suggest that the route to advanced eusociality in bees was mediated by many small changes in many genes and processes, and not by notable expansion or depauperation. Expand
The evolution of social parasitism in Acromyrmex leaf-cutting ants: a test of Emery’s rule
A molecular phylogeny using partial sequences of cytochrome oxidase I and II of about half of the known Acromyrmex species including two social parasites, their hosts and all congeneric species occurring sympatrically shows that the two inquiline parasites represent two separate origins of social parasitism in the genus Acromymex.

Polyphenism in social insects: insights from a transcriptome-wide analysis of gene expression in the life stages of the key pollinator, Bombus terrestris
Detailed analyses of immune and olfaction gene expression across phenotypes demonstrated how transcriptomic analyses can inform the understanding of processes central to the biology of B. terrestris and the social Hymenoptera in general. Expand
Differential gene expression in queen–worker caste determination in bumble-bees
The results suggest that caste determination in B. terrestris involves a difference not so much in the identity of genes expressed by queen- and worker-destined larvae, but primarily in the relative timing of their expression. Expand
High reproductive skew in tropical hover wasps
It is suggested that high skew in L. flavolineata may result from strong ecological constraints and a relatively high probability that a subordinate will eventually inherit the dominant, egg–laying position. Expand
Radio-Tagging Technology Reveals Extreme Nest-Drifting Behavior in a Eusocial Insect
It is demonstrated that drifting cannot be explained through social parasitism, queen succession, mistakes in nest identity, or methodological bias, and workers appear to gain indirect fitness benefits by helping on several related colonies in a viscous population structure. Expand
Bumblebee family lineage survival is enhanced in high-quality landscapes
It is shown that the survival of family lineages from the summer worker to the spring queen stage in the following year increases significantly with the proportion of high-value foraging habitat within 250–1,000 m of the natal colony, providing evidence for a positive impact of habitat quality on survival and persistence between successive colony cycle stages in bumblebee populations.
