Research at Carlos III University (Universidad Carlos III) in Madrid (Universidad Carlos III - UC3M) is developing an algorithm, based on ants´ behavior when they are searching for food, which accelerates the search for relationships among elements that are present in social networks. One of the main technical questions in the field of social networks, whose use is becoming more and more generalized, consists in locating the chain of reference that leads from one person to another,...

Ant queens get better at laying eggs as they get older, researchers report in the Apr. 11 issue of the open access journal PLoS ONE. Furthermore, this high egg-laying rate did not shorten the queens' life spans, as would have been expected based on many other organisms. The researchers, led by Juergen Heinze at the University of Regensburg in Germany, found that the egg laying rates of ant queens from the species Cardiocondyla obscurior steadily increased as the queens aged, unlike the...

Brett Smith for RedOrbit.com Discovery of a new giant wasp species last year has led to the discovery of an even larger species than had been sitting in a collection for 80 years. Megalara garuda hails from the Indonesian island of Sulawesi, the same island where a team led by professor Lynn Kimsey (UC Davis) discovered the wasp´s slightly smaller relative Dalara garuda. Both species belong to the digger wasp family, a diverse group of wasps that sting and paralyze prey insects....

Researchers Look Into Hoverfly Disguises
2012-03-23 08:46:47

Mimicry in the animal kingdom is a useful tool that many insects employ to make themselves appear more fierce in order to escape from becoming a meal. However, researchers have been puzzled as to how some of the worst mimickers still seem to escape certain demise. Researchers at Carleton University in Ottawa, Canada set out to find the nature of mimicry in one of these imperfect impersonators: the hoverfly. Some hoverflies have evolved to be nearly indistinguishable from bees and wasps,...

Ants Can Learn Vibrational And Magnetic Landmarks
2012-03-09 03:00:15

Ants are equipped with a number of sophisticated navigation tools, including the ability to both learn and use vibrational and magnetic landmarks, as reported Mar. 7 in the open access journal PLoS ONE. Cornelia Buehlmann, led by Bill Hansson and Markus Knaden of the Max Planck Institute in Germany, trained desert ants with magnetic and vibrational landmarks relative to their nest. Then they tested the ants and showed that the training did in fact help them find their nest. Importantly,...

The long-term impact of climate change on natural communities of wild animals could be better understood thanks to a new study The long-term impact of climate change on natural communities of wild animals could be better understood thanks to a new study. The research will help predict how migration of animals or changes to their habitats associated with climate change could impact on the evolution of relationships between predators and their prey. Scientists have shed light on how...

Cunning Super-parasitic Wasps Sniff Out Protected Aphids And Overwhelm Their Defenses
2012-02-23 18:00:20

In the war between parasite and host, the parasitic wasp, Aphidius ervi, and the pea aphid, Acyrthosiphon pisum, are locked in a battle for survival. New research published in BioMed Central's open access journal BMC Biology shows that this cunning parasite sniffs out differences between protected and unprotected aphids, and alters its egg-laying strategy, in order to overwhelm aphid defenses and ensure survival of wasp offspring. The wasp, A. ervi, lays an egg inside the pea aphid, where...

Ants Remember Their Rivals' Scent
2012-02-22 05:49:02

Researchers from the University of Melbourne report they have found that ant colonies share a collective memory for the odor of ants in rival nests. According to the new research, the ants use the information to identify the rival ants and compete, similar to how sports fans know each other by wearing their teams' colors. Study leader Professor Mark Elgar from the University's Department of Zoology said the ant colony's collective memory helps give an edge in a competitive world by...

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...
