Japanese honeybees use heat and carbon dioxide to kill their natural predator, the giant hornet.The bees form a "bee ball" in order to smother the predator, and kill the hornets within 10 minutes of their capture within the ball.Japanese hornets feast on the honeybee's nests and can consume their larvae.According to research, which appears in the journal Naturwissenschaften, if bees spot the attacker in time, they can stop them with their powerful "bee ball" defense.Although, researchers...

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...

The prestigious Smithsonian Museum has been overrun with insects. A brand new exhibit, "Farmers, Warriors, Builders: The Hidden Life of Ants," debuts Saturday at the National Museum of Natural History and is open through Oct. 10. The display will include a living leaf-cutter ant colony from Ted Schultz, the museum's curator of ants. Also on display is a 6-foot-tall cast of an ant colony collected by Walter Tschinkel, a student of ant-nest architecture at Florida State University. There will...

Residents of northwestern Arkansas say they are being plagued by ants looking for somewhere to get out of the rain. I'm getting disgusted with them, Vi McCullen of Rogers told KHBS/KHOG-TV, Fayetteville, Ft. Smith. Spray them and everything but they always come back. Cory Ward of West Termite and Pest Management said that ants come into houses looking for food. But he told the television station that the problem is far worse this year because of recent heavy rain. The ground is so saturated,...

Four species of tiny flies that lay eggs in fire ants have been imported into Texas in an effort to reduce the numbers of the stinging invaders. The phorid flies effectively turn fire ants into zombies, the Fort Worth (Texas) Star-Telegram reported Tuesday. The egg that hatches in a fire ant produces a maggot that eats the ant's brain, researchers at Texas A&M and the University of Texas say. It's a tool -- they're not going to completely wipe out the fire ant, but it's a way to control...

U.S. entomologists say they have discovered how ants know when a nestmate has died and its time to remove the body from the colony. University of California-Riverside scientists say when an ant dies its body is quickly picked up by living ants and removed, thus limiting the risk of colony infection by pathogens from the corpse. Up to now most entomologists theorized dead ants release chemicals created by decomposition, thereby signaling their death. But in the new study, scientists working on...

UC Riverside entomologists offer evidence for a mechanism: decrease in chemical signals produced by living ants When an ant dies in an ant nest or near one, its body is quickly picked up by living ants and removed from the colony, thus limiting the risk of colony infection by pathogens from the corpse. The predominant understanding among entomologists "“ scientists who study insects "“ was that dead ants release chemicals created by decomposition (such as fatty acids) that signal...

Nature is full of mutually beneficial arrangements between organisms"”like the relationship between flowering plants and their bee pollinators. But sometimes these blissful relationships have a dark side, as Harvard biologist Megan Frederickson describes in an article for the May issue of The American Naturalist. Generally, the relationship between ants and plants is a great example of biological mutualism. Myrmecophyte plants"”otherwise known as ant-plants"” often provide...

British scientists fitted rock ants with tiny radio-frequency ID tags to determine the process by which ants select a new home. University of Bristol researcher Elva Robinson and colleagues gave the ants the choice of a nearby poor nest or a good nest located farther away. The researchers found the colonies selected the superior site although it was nine times farther away than the alternative. And, the scientists said, the best nest was chosen despite the fact that very few individual ants...

Dr Elva Robinson and colleagues in the University's School of Biological Sciences fitted rock ants with tiny radio-frequency identification tags, each measuring 1 / 2,000 (one two-thousandth) the size of a postage stamp, then observed as they chose between a poor nest nearby and a good nest further away. The ant colonies showed sophisticated nest-site choice, selecting the superior site even though it was nine times further away than the alternative. The best nest was chosen, despite the fact...

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,...
