Future queen or tireless toiler? A paper wasp's destiny may lie in the antennal drumbeats of its caretaker. While feeding their colony's larvae, a paper wasp queen and other dominant females periodically beat their antennae in a rhythmic pattern against the nest chambers, a behavior known as antennal drumming. The drumming behavior is clearly audible even to human listeners and has been observed for decades, prompting numerous hypotheses about its purpose, says Robert Jeanne, a professor...

Social status in paper wasps is established earlier in life than scientists thought, says a study published this month in the journal PLoS ONE. While many social insects have distinct social classes that differ in appearance and are fixed from birth, paper wasp society is more fluid "” all castes look alike, and any female can climb the social ladder and become a queen. Now, molecular analysis reveals that paper wasp social hierarchy is less flexible than it appears. Queens diverge from...

They are both nest-building social insects, but paper wasps and honey bees organize their colonies in very different ways. In a new study, researchers report that despite their differences, these insects rely on the same network of genes to guide their social behavior. The study appears in the Proceedings of the Royal Society B: Biological Sciences. Honey bees and paper wasps are separated by more than 100 million years of evolution, and there are striking differences in how they divvy up the...

Standing out in a crowd is better than blending in, at least if you're a paper wasp in a colony where fights between nest-mates determine social status. That's the conclusion of a study by University of Michigan researchers published online this week in the journal Evolution. "It's good to be different, to wear a nametag advertising your identity," said graduate student Michael Sheehan, who collaborated on the research with evolutionary biologist Elizabeth Tibbetts. In earlier research,...

Which came first, social dominance or big brains? Wasps may tell There's new evidence supporting the idea that bigger brains are better. A study of a tropical wasp suggests that the brainpower required to be dominant drives brain capacity. University of Washington researchers have found that key processing regions in the brains of both males and females of one wasp species not only increased in size with age but were also associated with being dominant. The study also showed different...

Paper Wasps are social wasps and make up the genus Polistes. They form small colonies with umbrella-shaped nests in sheltered spots, and are quite mild-mannered. They feed on caterpillars and other soft-bodied insects, most of them pests. Despite the use of the proper name, most social wasps make nests from paper, although some tropical wasp species such as Listenogaster Flavolineata use mud, a far more easy resource for the wasp to collect. The larger colonial species, Yellowjackets,...

The Cicada Killer Wasp is a large, solitary wasp so named because is hunts cicadas and provisions its nest with them. In North America it is sometimes called the Sand Hornet, although it is not a hornet, which belong to the family Vespidae. Taxonomy The North American cicada killer wasps all belong to the genus Sphecius, of which there are 21 species worldwide. The four cicada-killing species in North America are: Sphecius speciosus (Drury, 1773), the Eastern Cicada Killer, occurs in...
