UC Riverside biologists say young male crickets grow larger in the presence of sexually mature adult male crickets In the animal kingdom, sexual signals often are manifested as displays of bright coloration or, in the case of crickets, as loud song. Adult male crickets produce loud song to attract females, but the song, which permeates the environment, can be overheard also by unintended receivers - such as young males unable to produce song due to a mutation they carry. Until now researchers...

It makes your skin crawl"”a bug that crawls onto your lips while you sleep, drawn by the exhaled carbon dioxide, numbs your skin, bites, then gorges on your blood. And if that's not insult enough, it promptly defecates on the wound-and passes on a potentially deadly disease. Now Jean-Paul Paluzzi, a PhD candidate in biology at the University of Toronto Mississauga, believes that manipulating physiology to prevent the insects from leaving their messy calling card represents the best hope...

The hair-like structures used by birch caterpillars to communicate warnings may have evolved from walking, researchers from Carleton University in Ottawa, Canada have discovered. The research team, led by Dr. Jayne Yack from the university, published their findings in the Nature Communications journal. Their report was entitled "The evolutionary origins of ritualized acoustic signals in caterpillars" and was published in the April 12 issue. In the abstract accompanying their report, the...

Study shows how birds, bats and lizards play their roles in preserving plant species in face of global climate change Add insect-feeding birds, bats and lizards to the front lines of the battle against global climate change. Summarizing the results of more than 100 experiments conducted on four continents, UC Irvine ecologist Kailen A. Mooney and colleagues found that these insect-gobbling animals increase plant growth by reducing the abundance of plant-feeding insects and the damage they do...

Lions, tigers and bears top the ecological pyramid"”the diagram of the food chain that every school child knows. They eat smaller animals, feeding on energy that flows up from the base where plants convert sunlight into carbohydrates. A new study examines complex interactions in the middle of the pyramid, where birds, bats and lizards consume insects. These predators eat enough insects to indirectly benefit plants and increase their growth, Smithsonian scientists report. "Our findings...

Scientists in Brazil are reporting for the first time that coffee beans contain proteins that can kill insects and might be developed into new insecticides for protecting food crops against destructive pests. Their study, which suggests a new use for one of the most important tropical crops in the world, appears in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication. Peas, beans and some other plant seeds contain proteins, called globulins, which ward off insects. Coffee...

Hebrew University researchers developing 'breakfast of champions' An improved method for sustainable pest control using "super-sexed" but sterile male insects to copulate with female ones is being developed by agricultural researchers at the Hebrew University of Jerusalem. The scientists thus hope to offer yet another efficient and promising avenue for supplying produce to the market by eliminating pests without damage to the environment. An assortment of chemicals, such as DDT, have been...

ITHACA, N.Y. -- Cornell researchers have found a protein that may lead to a new way to control mosquitoes that spread dengue fever, yellow fever and other diseases when they feed on humans: Prevent them from urinating as they feed on blood. The work may lead to the development of new insecticides to disrupt the mosquito's renal system, which contributes to a mosquito's survival after feeding on blood. Aedes aegypti mosquitoes transmit the virus that causes dengue fever, putting 40...

Observing the aerial maneuvers of fruit flies, Cornell University researchers have uncovered how the insects "“ when disturbed by sharp gusts of wind "“ right themselves and stay on course. Fruit flies use an automatic stabilizer reflex that helps them recover with precision from midflight stumbles, according to observations published online today (March 1, 2010) in Proceedings of the National Academy of Sciences. Learning from the biological world could help the mechanical, as...

Any way you look at it -- by sheer weight, species diversity or population -- the hard-shelled, joint-legged creepy crawlies called arthropods dominate planet Earth. Because of their success and importance, scientists have been trying for decades to figure out the family relationships that link lobsters to millipedes and cockroaches to tarantulas and find which might have come first. In a scientific and technological tour de force that was nearly a decade in the making, a team of scientists...

Tetragnatha extensa
2013-10-09 13:17:36

Tetragnatha extensa is a species of spider found across the Northern Hemisphere. It has an elongate body, up to .43 inches long, and assumes a straight line posture when it is alarmed. It lives on low vegetation in damp areas and consumes flying insects which it catches in its web. This spider has a stretched out, cream colored body. The males are smaller than the females at around .35 inches body length, compared to .43 inches in the females. The four pairs of legs are long and a dark...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
