Methylation and gene expression differences between reproductive and sterile bumblebee workers

Evolution Letters, 2019
Phenotypic plasticity is the production of multiple phenotypes from a single genome and is notably observed in social insects. Multiple epigenetic mechanisms have been associated with social insect plasticity, with DNA methylation being explored to the ...

Contribution of Epigenetic Mechanisms in the Regulation of Environmentally-Induced Polyphenism in Insects

Insects, 2021
Many insect species display a remarkable ability to produce discrete phenotypes in response to changes in environmental conditions. Such phenotypic plasticity is referred to as polyphenism.

Morphological Caste Differences in Three Species of the Neotropical Genus Clypearia (Hymenoptera: Polistinae: Epiponini)

Psyche: A Journal of Entomology, 2010
Clypearia is a rare genus of swarm-founding Neotropical wasp whose biology is very little known. Morphological castes differences, condition of ovaries, relative age, and color pattern differences were analyzed in three species of Clypearia ...

Genome-Wide Differential DNA Methylation in Reproductive, Morphological, and Visual System Differences Between Queen Bee and Worker Bee (Apis mellifera)

Frontiers in Genetics, 2020
There are many differences in external morphology and internal physiology between the Apis mellifera queen bee and worker bee, some of which are relevant to beekeeping production.

Unexpected worker mating and colony-founding in a superorganism

Nature Communications, 2023
The emergence of caste-differentiated colonies, which have been defined as ‘superorganisms’, in ants, bees, and wasps represents a major transition in evolution.

The genus Lepisiota Santschi, 1926 of the Arabian Peninsula with the description of a new species, Lepisiota elbazi sp. nov. from Oman, an updated species identification key, and assessment of zoogeographic affinities [PDF]

Journal of Hymenoptera Research, 2020
This study updates and summarizes information on the taxonomy and status of the Arabian Lepisiota fauna. We describe and illustrate the new species Lepisiota elbazi sp. nov. from the Dhofar Governorate, Oman based on the worker caste.

Sexual dimorphism as a facilitator of worker caste evolution in ants

Ecology and Evolution, 2023
Ant societies are primarily composed of females, whereby labor is divided into reproductive, or queen, and non‐reproductive, or worker, castes. Workers and reproductive queens can differ greatly in behavior, longevity, physiology, and morphology, but ...

The effect of DNA methylation on bumblebee colony development

BMC Genomics, 2021
Background Although around 1% of cytosines in bees’ genomes are known to be methylated, less is known about methylation’s effect on bee behavior and fitness.
