Researchers at the University of Michigan recently studied paper wasps and their ability to recognize wasp faces. They discovered that the species Polistes fuscatus has a special ability to learn faces and retain what they learn. According to Michael Sheehan, who worked on the research with evolutionary biologist Elizabeth Tibbetts, “Wasps and humans have independently evolved similar and very specialized face-learning mechanisms, despite the fact that everything about the way we see...

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...

Scientists trying to understand how the brains of animals evolve have found that evolutionary changes in brain structure reflect the types of social interactions and environmental stimuli different species face.The study is the first to compare multiple species of related animals, in this case social wasps, to look at how roles of individuals in a society might affect brain architecture. The research looks at brain structure differences between species, asking how the size of different brain...

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,...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
