Flies follow horizontal edges to regulate altitude, says a team of researchers from the California Institute of Technology (Caltech). This finding contradicts a previous model, which posited that insects adjust their height by visually measuring the motion beneath them as they fly. This mechanism for controlling altitude"”in which the insects use their eyes to track horizontal edges in their environment"”is very similar to the strategy insects use to steer left and right, the...

What can you learn from the 120 year-old body of a parasitoid wasp? Using material from museum collections, researchers writing in the open access journal BMC Evolutionary Biology report that they can tell how males wasps court their females, based on dead specimens. Parasitoid wasps are one of the most abundant groups of organisms on the planet. Their diversity makes it very hard to study behaviors across many species. Seraina Klopfstein from the Natural History Museum of Bern, Switzerland,...

The defining feature of social insects is that societies contain queens, which specialise in laying eggs, as well as workers, which are mostly infertile but take care of the offspring and the nest. However, when the queen dies or is re-moved, workers begin laying eggs of their own. Previous observations have suggested that queens possess a specific pheromone which keeps the workers infer-tile, but the pheromone has never been identified except in the well-studied honeybee. Queen pheromones...

There really is a balance of nature, but as accepted as that thought is, it has rarely been studied. Now Washington State University researchers writing in the journal Nature have found that more balanced animal and plant communities typical of organic farms work better at fighting pests and growing a better plant. The researchers looked at insect pests and their natural enemies in potatoes and found organic crops had more balanced insect populations in which no one species of insect has a...

Researchers look for small control organism "The small size of an alien insect that feeds on a native tree from the western Pacific island of Guam allows it to hide in cracks and other locations that are out of reach for its only local natural enemy," said UOG entomologist Aubrey Moore. Moore has teamed up with UOG ecologist Thomas Marler to study the relationship between the native cycad tree, known as "fadang" in the Chamorro language, and a minute alien insect pest called cycad aulacaspis...

Insects may have tiny brains the size of a pinhead, but the latest research from the University of Adelaide shows just how clever they really are. For the first time, researchers from the University's Discipline of Physiology have worked out how insects judge the speed of moving objects. It appears that insect brain cells have additional mechanisms which can calculate how to make a controlled landing on a flower or reach a food source. This ability only works in a natural setting. In a paper...

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...

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...

Entomology, a branch of arthropodology, is the study of insects. In the past, the term insect was used to refer to species from other phyla or groups including arachnids, slugs, and earthworms. This view of entomology is still used in informal settings today. Entomology extends through cross sections of science including paleontology, biochemistry, and nutrition, among many others. There are 1.3 million species of insects throughout the world, so entomology covers a large base of research...

Myrmecology

Myrmecology, a branch of entomology, is the study of ants that has focused on many factors about ants, including evolution and social systems. William Morton Wheeler first used the term myrmecology, but the study of ants predates the usage of the term, going back to ancient references of ants. Auguste Forel, a Swiss psychologist, conducted the first scientific studies of ants, focusing on the roles of instinct and learning in a society. He published Les fourmis de la Suisse in 1874 after...

Inchman, Myrmecia forficate
2013-07-10 12:28:46

The inchman (Myrmecia forficate) is a species of bull ant that can be found in Australia, in a range that includes Tasmania and possibly southeastern areas of Australia. This species is gregarious, living in colonies like most other ant species, but it forages for food alone. Nests often go unseen and are typically found under rocks.  It reaches an average body length of up to one inch long, the trait from which it received its common name. The inchman is both a scavenger and a...

Rhithrogena germanica, known as the March brown mayfly in in the British Isle, is a species of mayfly that can be found throughout northern and central areas of Europe. Its range includes the River Tweed in England, Hesse in Germany, Denmark, Poland, and France. It was first described by Alfred Edwin Eaton, who studied a male specimen from the River Rhine. Rhithrogena germanica begins its lifecycle in the larval stage, as a water dwelling naiad that is typically found in fast flowing,...

The Argema mittrei, more commonly known as the Comet or Moon Moth, is an endangered species. It is a native of Madagascar and that is the only place where one can observe them in the wild. This large silk moth can be bred in captivity and is one of the world's largest moths. Males have an average wing span of nearly 8 inches and a tail span of almost 6 inches. The lifespan of an adult moth is only 4-5 days and they are capable of reproduction from day 1. Their cocoons are uniquely...
