Insects could replace many lab mice used for evaluating the safety of certain drugs, researchers reported on Tuesday. Dr. Kevin Kavanagh, from the National University of Ireland, and colleagues found that insects, such as moths, and fruit flies, could safely be used to replace mice in lab testing for drug safety. Kavanagh presented his findings to the Society for General Microbiology's meeting at Heriot Watt University, Edinburgh on Tuesday. The team showed that neutrophils "“ a type of...

Water striders, the familiar semi-aquatic bugs gliding across the lake at the cottage, have a novel body form that allows them to walk on water.  This was not always the case.  Achieving the gliding ability required the evolution of a unique arrangement of the legs, with the mid-legs greatly elongated. Scientists at the University of Toronto's Department of Ecology and Evolutionary Biology have discovered the gene behind this evolutionary change.Called the Hox gene, Ultrabithorax,...

A U.S. researcher says climate change affects are as important to animals as they are to insects such as butterflies and beetles. Animals such as polar bears, tigers and dolphins are tremendously important, but mostly because they help define how we think about our relationship with the natural world, University of Notre Dame Assistant Professor Jessica Hellmann said. But when it comes to the functioning of ecosystems, insects are where it's at. They carry diseases, they pollinate and they...

Cicadas - better known for providing the soundtrack of our hot summer are remarkably interesting animals, they are the longest living insects "“ 17 years for some species "“ but spent 99% of this time underground to then emerge for a few weeks, reproduce and finally die. Now a study of north-African and Mediterranean cicadas by scientists in Portugal and the UK uncover yet more interesting data on the group by revealing that these species although differentiated by their mating...

Early relatives of spiders that lived around 300 million years ago are revealed in new three-dimensional models, in research published today in the journal Biology Letters.Scientists at Imperial College London have created detailed 3D computer models of two fossilized specimens of ancient creatures called Cryptomartus hindi and Eophrynus prestvicii, closely related to modern-day spiders. The study reveals some of the physical traits that helped them to hunt for prey and evade predators.The...

Chemicals camouflage bugs, pitcher plant colors don't help attract prey, specialist caterpillars survive better than generalistsAnimals and plants communicate with one another in a variety of ways: behavior, body patterns, and even chemistry. In a series of talks at the Ecological Society of America's annual meeting, to be held August 3-7 in Albuquerque, New Mexico, ecologists explore the myriad adaptations for exchanging information among living things.Bugs pretending to be ants are...

Increasingly, human urban development overlaps with habitat for wild animals and plants, creating environments that degrade natural landscapes. But people, animals and plants all have in common the need for healthy, sustainable freshwater ecosystems. In a series of presentations at the Ecological Society of America's Annual Meeting, ecologists present research results that guide efforts to balance an increasingly urbanized society with the need to conserve and protect water and aquatic...

An official with the Ohio Department of Wildlife said a rare pink katydid that was slated to go on display at the Ohio State Fair has been killed by a wasp. Jim McCormac of the Ohio Division of Wildlife said the katydid, discovered July 19 at the Killdeer Plains Wildlife Area in Wyandot County and slated to go on display at a fair, which began Wednesday, was killed after a parasitic wasp injected its eggs into the insect and the offspring ate their way out, The Columbus (Ohio) Dispatch...

If it were up to Jessica Hellmann, insects such as butterflies and beetles would wield just as much conservation clout as traditional conservation icons, such as polar bears, tigers and dolphins.Why?"Animals such as polar bears, tigers and dolphins are tremendously important, but mostly because they help define how we think about our relationship with the natural world," says Hellmann. "But when it comes to the functioning of ecosystems, insects are where it's at."Why are insects so...
