2014-01-10 06:37:59

Pensoft Publishers A group of scientists from the University of Mainz and the Senckenberg Museum of Natural History Goerlitz, headed by Susanne Foitzik and Bernhard Seifert, recently described a new slave-making ant species from the eastern USA. They baptized the new ant Temnothorax pilagens – from pilere (Latin): to pluck, plunder or pillage. The paper was published in the open access journal ZooKeys. In contrast to the famous slave-hunting Amazon Ants whose campaigns may include up...

Ants Grow Their Thoracic Segments To Match The Tasks They Perform
2014-01-07 07:22:27

Instituto Gulbenkian de Ciencia It has now been discovered that the specialization of queen and worker ants goes beyond the presence or absence of wings. In a study published in the open access scientific journal eLife, Roberto A. Keller and Patrícia Beldade from the Instituto Gulbenkian de Ciência (IGC, Portugal), in collaboration with Christian Peeters from Université Pierre et Marie Curie (France), showed that ants grow the size of their thoracic segments differently according to the...

Nine Beautiful New Wasp Species From China
2013-12-13 14:35:29

Pensoft Publishers A new study provides seventeen records of the cuckoo wasp genus Cleptes from China, nine of which are beautifully colored new to science species. The study, published in the open access journal ZooKeys, is the first revision of the genus from China, providing morphological data and illustrations. The revised genus belongs to the engaging cuckoo wasp family Chrysididae. As their common name suggests, these wasps have some peculiar parasitoid nesting habits. Often...

We know more about wildlife this week, thanks to research by two Canadian teens. Teens from Ottawa and rural British Columbia published their research in this week’s issue of a scientific journal, The Canadian Field-Naturalist. Their research on wasps and leaf disease reveal that a Canadian wasp is an efficient killer of an agricultural pest, and a little-known fungus is hurting Highbush Cranberries. Both research articles were subject to the same peer-review process and met the same...

Fossil Evidence Indicates Fig Wasps Were Here Long Before Fig Trees
2013-12-06 07:57:54

April Flowers for redOrbit.com - Your Universe Online Researchers are puzzled by a 115-million-year-old fossilized wasp from northeast Brazil. The puzzle rests in the wasp's ovipositor, the organ through which it lays its eggs. The fossilized wasp's ovipositor looks a lot like those of present-day wasps that lay their eggs in figs. The researchers say that the problem is that figs arose around 65 million years after this wasp was alive. The wasp belongs to the Hymenoptera superfamily...

Fossils Clarify Origins Of Wasps And Their Kin
2013-12-04 19:00:47

Pensoft Publishers Wasps, bees, ants and relatives comprise the megadiverse insect order Hymenoptera, the third most speciose animal group on Earth, far surpassing the number of known vertebrate species. All the four most diverse orders of animals (beetles, butterflies, wasps, and true flies) belong to the group of insects with complete metamorphosis, i.e. having a dormant pupa, jointly known as Holometabola. Other holometabolans are lacewings, alderflies, dobsonflies, snakeflies,...

Amazing Viscoelasticity Observed In Structures Comprised Of Fire Ants
2013-11-27 08:55:06

[ Watch the Video: Fire Ants Being Smashed by Petri Dish ] redOrbit Staff & Wire Reports - Your Universe Online Fire ants are capable of joining together to form a waterproof structure capable of bouncing back to its original shape when stretched or compressed, according to research presented Tuesday at the annual meeting of the American Physical Society's (APS) Division of Fluid Dynamics (DFD). Researchers from the Georgia Institute of Technology explain that these ants can...

Two New Wasp Species Added To Rare Genus Abernessia
2013-11-25 10:31:21

Pensoft Publishers Two new beautiful wasp species are added to the rare pompilid genus Abernessia, which now contains a total of only four known species. The two new species A. prima and A. capixaba are believed to be endemic for Brazil alongside the rest of the representatives of the genus. Both wasps are distinguished by the large size (almost 3cm in length) and the beautiful black color with metallic shine typical for the family. The study was published in the open access journal...

Smaller Islands Have Shorter Food Chains
2013-11-22 09:07:08

University of Helsinki That smaller islands will typically sustain fewer species than large ones is a widespread pattern in nature. Now a team of researchers shows that smaller area will mean not only fewer species, but also shorter food chains. This implies that plant and animal communities on small islands may work differently from those on large ones. Top predators the first to go Working across a set of 20 islands off the Finnish coast, a group of Finnish scientists found that a...

Hardworking Sisters Allow Insect Colonies To Thrive
2013-11-21 14:09:25

University of Edinburgh They are among the animal kingdom's most industrious workers … now a study reveals why colonies of ants and bees depend on females for their success. Altruistic workers in social insect colonies – such as ants, bees and wasps – are more likely to be female, because their maternal instincts make them better at caring for the queen's offspring. The findings come from a study of who does what in these highly organized insect societies. In these species, it...

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...
