NEW ORLEANS -- Entomologists believe that Hurricane Katrina provided them with a golden opportunity to knock out, or at least squash, the fire ant population in this city. Flood waters rid many neighborhoods of the stinging ants and on Thursday crews began spreading deadly bait in parks and along levees to kill the ant colonies and nests that did survive. The citywide eradication plan, backed by large donations of bait by pesticide companies, also seeks to engage neighborhood groups and...

WASHINGTON -- Ants evolved far earlier than previously believed, as far back as 140 million to 168 million years ago -- and they have plants to thank for their diversity, U.S. researchers reported on Thursday. A team at Harvard University who used a genetic clock to reconstruct the history of ants found the ant family first arose more than 40 million years earlier than previously thought, but did not diversify into different genera and species until flowering plants came onto the scene. The...

LONDON (Reuters) - British researchers said on Wednesday they had uncovered the first proof of teaching in non-human animals -- ants showing each other the way to food. The ants studied over two years by scientists from Bristol University used a technique known as tandem running -- one ant led another ant from the nest to a food source. It was a genuine case of teaching as ant leaders observed by Professor Nigel Franks and Tom Richardson slowed down if the follower got too far behind. If the...

CHAMPAIGN, Ill. -- Many insects enter the United States accidentally, as hitchhikers on various plants imported in commerce, but how many really stay? Conventional thinking says the answer is in the numbers of both insects and times they enter, but new findings to be published in the Proceedings of the National Academy of Sciences suggest that opportunity alone is no guarantee of a successful invasion. Of 232 species of ants that entered U.S. ports uninvited from 1927 to 1985, 28 species...

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,...
