Studying ants to find out how colony size affects patterns of behavior and energy use How does size affect the organization and physiology of superorganisms such as bacterial communities, insect colonies or human cities? James Waters and Tate Holbrook, graduate students in the School of Life Sciences at Arizona State University, work on answering this question by studying how colony size affects the patterns of behavior and energy use in ant colonies. Social insect colonies are excellent...

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...

As every middle-school child knows, in the process of photosynthesis, plants take the sun's energy and convert it to electrical energy. Now a Tel Aviv University team has demonstrated how a member of the animal kingdom, the Oriental hornet, takes the sun's energy and converts it into electric power "” in the brown and yellow parts of its body "” as well. "The interesting thing here is that a living biological creature does a thing like that," says physicist Prof. David Bergman of...

When their razor-sharp mandibles wear out, leaf-cutter ants change jobs, remaining productive while letting their more efficient sisters take over cutting, say researchers from two Oregon universities. Their study -- appearing online ahead of regular publication in the journal Behavioral Ecology and Sociobiology -- provides a glimpse of nature's way of providing for its displaced workers. "This study demonstrates an advantage of social living that we are familiar with -- humans that can no...

But in Britain workers are docile and "Ëœapathetic' compared with 'revolutionary' workers in Spain A new study analyzing how complex, highly-evolved societies are organized in nature has found that it is workers that play a pivotal role in creating well-ordered societies where conflict is minimized. For when it comes to determining who reproduces in ants, University of Leicester biologists have found the humble worker is queenmaker "“ it is they who choose their queen. This...

In the complex world of ant-plant partnerships, serial monogamy can help trees maximize their evolutionary fitness, a new University of Florida study shows. Trees that sequentially partner with multi-species sets of ants produce more offspring than trees that maintain a lifelong association with any single ant "” even when those sets include ant species that appear to harm the tree, said Todd Palmer, a UF biology professor. The study has broad implications because many of the world's...

A species of acacia tree in Eastern Africa seems to be protected from elephants by ants, according to new research from scientists at the Universities of Wyoming and Florida. The researchers conducted a series of studies in Kenya, and found that the acacia trees in areas heavily trafficked by elephants simply get pummeled without protection from their tiny ant bodyguards. "It really is a David-and-Goliath type of story, where these little ants are up against these huge herbivores, protecting...

Research may help unlock the mysteries of human aging and behaviorScientists have finally sequenced the entire genome of an ant, actually two very different species of ant, and the insights gleaned from their genetic blueprints are already yielding tantalizing clues to the extraordinary social behavior of ants.A result of a ground-breaking collaborative research project led by Danny Reinberg, PhD, professor of biochemistry at NYU Langone Medical Center and a Howard Hughes Medical Institute...

New research shows that when some fence lizards are attacked by fire ants they "stress out"-- a response that actually helps the species to survive by heightening the animal's awareness of imminent danger. Tracy Langkilde, assistant professor of biology at Penn State University, found that lizards living in areas of the southeastern United States, where large numbers of fire ants also live, have elevated levels of stress hormones, called glucocorticoids. The stress-hormone study comes on the...

Mate selection, foraging and defense mechanisms explored at ESA's Annual Meeting In this time of global change, understanding the basics of animal behavior and environmental interactions is just as important as predicting and planning for widespread impacts. Ecological scientists will assess the fundamentals of animal behavior"”such as plant toxin detection in bushbaby foraging"”and current adaptations to global change"”like defense mechanisms of native lizards to red...

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,...
