A group of 'friend or foe' scent molecules have been isolated from colonies of Argentine ants. Researchers writing in the open access journal BMC Biology identified and synthesized the scents, describing how applying them to worker ants resulted in attacks from their former colony-mates. Neil Tsutsui and colleagues, from the University of California, Berkeley, USA, worked with a team of researchers from the University of California, Irvine to carry out the ant experiments. He said, "Chemical...

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,...

First evidence of multiple tool use suggests 'sustainable' food-harvesting techniques Chimpanzees in the Congo have developed specialized 'tool kits' to forage for army ants, reveals new research published today in the American Journal of Primatology. This not only provides the first direct evidence of multiple tool use in this context, but suggests that chimpanzees have developed a 'sustainable' way of harvesting food. A team from the Goualougo Triangle Ape Project, led by Dr Crickette Sanz,...

A study in the September issue of The American Naturalist describes new details about a fungal parasite that coerces ants into dying in just the right spot"”one that is ideal for the fungus to grow and reproduce. The study, led David P. Hughes of Harvard University, shows just how precisely the fungus manipulates the behavior of its hapless hosts.When a carpenter ant is infected by a fungus known as Ophiocordyceps unilateralis, the victim remains alive for a short time. The fungus,...

Chemicals camouflage bugs, pitcher plant colors don't help attract prey, specialist caterpillars survive better than generalistsAnimals and plants communicate with one another in a variety of ways: behavior, body patterns, and even chemistry. In a series of talks at the Ecological Society of America's annual meeting, to be held August 3-7 in Albuquerque, New Mexico, ecologists explore the myriad adaptations for exchanging information among living things.Bugs pretending to be ants are...

University researchers suggest that ants can accomplish a task more rationally than humans. However, this doesn't necessarily mean that people are "stupider" than ants, according to the research teams from Arizona State University and Princeton University. Study leaders Stephen Pratt and Susan Edwards say that humans and animals simply often make irrational choices when faced with very challenging decisions. Pratt wrote in the journal Proceedings of the Royal Society: Biological Sciences that...

A switch from annual to multiyear colonies and a willingness to feed just about any prey to their young have allowed invasive yellowjacket wasps to disrupt native populations of insects and spiders on two Hawaiian islands, a new study has found.By analyzing the DNA from bits of prey snatched from foragers returning to nests, ecologists from the University of California, San Diego, found that introduced yellowjacket wasps kill or scavenge prey from 14 different taxonomic orders of animals,...

A wasp is any insect of the order Hymenoptera and suborder Apocrita that is not a bee, sawfly, or an ant. The less familiar suborder Symphyta includes the sawflies and wood wasps, which differ from the Apocrita by having a broad connection between the thorax and abdomen. Also, Symphyta larvae are mostly herbivorous and "caterpillarlike", whereas those of Apocrita are largely predatory or parasitic. Most familiar wasps belong to the Aculeata, a division of the Apocrita whose ovipositors are...

Spider wasps, also called pompilid wasps or spider-hunting wasps, are insects belonging to a diverse family named Pompilidae, of the order Hymenoptera. Spider wasps are sometimes distinct from other wasps in features such as eye structure (no notch as in Family Vespidae), legs modified for grooming, and in having a groove dividing the mesopleuron (a region of the thorax) into halves. Larvae can also be identified by physical examination. Females are often larger than the males, with...

Yellowjackets are typically black-and-yellow wasps of the genus Vespula or Dolichovespula (though some can be black-and-white, the most notable of these being the bald-faced hornet, Dolichovespula maculata). They are characterized mostly by their distinctive combination of black-and-yellow color, small size (slightly larger than a bee), and entirely black antennae. They live in colonies and build globular paper nests. Workers are around 12-20 mm in length, depending on species, and feed on...

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.
