Potsdam Institute for Climate Impact Research (PIK) Ants are capable of complex problem-solving strategies that could be widely applied as optimization techniques. An individual ant searching for food walks in random ways, biologists found. Yet the collective foraging behavior of ants goes well beyond that, as a mathematical study to be published in the Proceedings of the National Academy of Sciences reveals: The animal movements at a certain point change from chaos to order. This happens...

bee biodiversity
2014-05-12 09:14:56

Brett Smith for redOrbit.com - Your Universe Online Farmers rely on bees to pollinate their crops and increase yields, and a new study from entomologists at North Carolina State University has found the biodiversity of bees in a local ecosystem can have a significant impact on crop yield. In the report, which was published in the journal PLOS ONE, the researchers showed that blueberry plants produce more seed and grow larger berries if they receive a more diverse range of bee species....

Study Shows Bumblebees Join Other Bees Already Safely Feeding On Flowers
2014-04-30 03:16:03

Queen Mary, University of London Bumblebees can distinguish between safe and dangerous environments, and are attracted to land on flowers popular with other bees when exposed to perilous situations, according to new research from Queen Mary University of London. The study published in the journal Proceedings of the Royal Society B, shows that past experience of predation causes bumblebees to join other bees already safely feeding on flowers. Co-author and PhD student Erika Dawson...

Parasitic Butterfly Larvae May Use Acoustic Signals To Infiltrate Ant Colonies
2014-04-10 15:57:05

PLOS Parasitic butterfly larvae may mimic ants' acoustic signals to aid in the infiltration of their host colonies, according to results published April 9, 2014, in the open access journal PLOS ONE by Marco Sala from University of Turin, Italy, and colleagues. Ants aggressively defend their colonies and nests, so successfully that these locations make a perfect shelter for another similar species to live in. However, ants have evolved a complex set of signals that allow colony members...

Attracting Or Repelling Insects Using Different Scents
2014-04-01 15:48:26

University of Zurich Flowering plants attract pollinating insects with scent from their flowers and bright colors. If they have become infested with herbivores like caterpillars, they attract beneficial insects like parasitic wasps with the help of scent signals from their leaves. The wasps then lay their eggs in the caterpillars and kill the parasites. Floral and foliar scents can, however, mutually reduce their attractiveness. That's why flowering plants face a dilemma: should they use...

Bumblebees Willing To Learn If There's A Sweet Treat Involved
2014-03-19 05:51:49

April Flowers for redOrbit.com - Your Universe Online A pair of new studies from the University of Guelph reveals that bumblebees might have tiny brains, but they are capable of remarkable feats, especially when offered a tasty reward. The researchers, Prof. Peter Kevan, of the School of Environmental Sciences, and PhD student Hamida Mirwan are studying bees’ ability to learn by themselves and from each other. The scientists found that bees are capable of learning to solve...

Specialization By Insect Species Is The Key
2014-03-14 14:54:57

University of Iowa Most of us already imagine the tropics as a place of diversity—a lush region of the globe teeming with a wide variety of exotic plants and animals. But for researchers Andrew Forbes and Marty Condon, there's even more diversity than meets the eye. In a paper published in the March 14 issue of the journal Science, Forbes and Condon report the discovery of extraordinary diversity and specialization in the tropics. The paper builds upon previous research conducted...

Jumping Spider Uses Ant As Bodyguard
2014-03-12 09:31:54

Springer Ants are the unlikely guardians of jumping spiders in their battle against aggressive spitting spiders A timid jumping spider uses the scent of ants as a secret weapon to save itself from becoming the somewhat soggy prey of the predatory spitting spider. The downside to this plan is that jumping spiders are also a favorite snack of its very own saviors. To overcome this additional hazard, the spider has made yet another plan in the form of an ant-proof nest, writes Ximena...

Pensoft Publishers An inventory of wild-caught caterpillars, its food plants and parasitoids, has been going on for more than 34 years in Area de Conservación Guanacaste (ACG), a protected area of approximately 1200 km2 in northwestern Costa Rica. As a result, more than 10,000 species of moths and butterflies are estimated to live in ACG. Their caterpillars are in turn attacked by many parasitoid wasps, also numbering thousands of species. However, most of those wasps have never been...

Worker Ants Link Bodies And Buoyant Broods To Protect Queen During Flood
2014-02-20 09:34:12

PLOS When facing a flood, ants build rafts and use both the buoyancy of the brood and the recovery ability of workers to minimize injury or death, according to a study published in PLOS ONE on February 19, 2014 by Jessica Purcell from University of Lausanne, Switzerland, and colleagues. Furthermore, the queen ant is placed in the middle and protected on all sides by the rafting ants. When put in harm's way, social animals are often able to work together to enhance the survival and...

Jack Jumper Ant, Myrmecia pilosula
2013-07-10 13:00:54

The jack jumper ant (Myrmecia pilosula), known by other names including the jumping jack or hopper ant, is a species of bull ant that can be found in Australia. Its range includes Tasmania, New South Wales, and rural areas of Victoria. This species is unique in that its genome only holds on set of chromosomes, which is the lowest number of chromosomes that any animal can hold. Like other bull ants, this species can build nests under rocks or under dirt mounds. The jack jumper reaches an...

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...

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...

The Bombyliids are a large family of flies with hundreds of genera. Their life cycles are not well known. Adults generally feed on nectar and pollen, thus are pollinators of flowers. They superficially resemble bees, thus are commonly called bee flies, and this may offer the adults some protection from predators. The larval stage are predators or parasitoids of other insect eggs and larvae. The adult females usually deposit eggs in the vicinity of possible hosts, quite often in the burrows...

The bumblebee is a flying insect of the genus Bombus in the family Apidae and a relative of the common honeybee. The bumblebee feeds on nectar and gathers pollen to feed its young. They are beneficial to humans and the plant world alike, and tend to be larger than other members of the bee family. Most bumblebee species are gentle. From this comes their original name: "Humblebee". Bumblebees are social insects that are known for their black and yellow striped bodies, a commonality among the...
