Polistes fuscatus

Penn State Aggression-causing genes appeared early in animal evolution and have maintained their roles for millions of years and across many species, even though animal aggression today varies widely from territorial fighting to setting up social hierarchies, according to researchers from Iowa State University, Penn State and Grand Valley State University. If these "mean genes" keep their roles in different animals and in different contexts, then perhaps model organisms -- such as bees...

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...

Fruit Flies Pickier Than You Think
2013-12-05 19:17:53

Cell Press On your kitchen counter, it might seem as though fruit flies will show up for just about any type of fruit you leave around for them. But when given a choice about where to lay their eggs, those flies will go for citrus most of the time, new work shows. The basis for that seemingly complex food preference is surprisingly simple, according to a report in the Cell Press journal Current Biology on December 5. It boils down to a single odorant receptor found on a single class of...

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...

Orchard Mason Bee, Osmia lignaria
2013-07-10 14:38:22

The orchard mason bee (Osmia lignaria), also known as the blue orchard bee, is a species of megachilid bee that is native to North America. Its range extends across the Rocky Mountains, where two subspecies are located. The nests of this species are made in natural hollows in which the bees will make separate rooms for larvae by creating walls with mud. The orchard mason bee can first be seen the early spring months, when temperatures reach about fifty-seven degrees Fahrenheit. Males leave...

It nests in burrows tunneled into the side of sandy banks. It does not form colonies. Like other bee-eaters, the Red-bearded Bee-eater is colorful and has a long tail. Its beak is curved downward and it has pointed wings. It is mostly green, with red coloration to the face that extends on to the throat feathers...

Spider wasps, also called pompilid wasps or spider-hunting wasps, are insects belonging to a diverse family named Pompilidae, of the order Hymenoptera. Spider wasps are sometimes distinct from other wasps in features such as eye structure (no notch as in Family Vespidae), legs modified for grooming, and in having a groove dividing the mesopleuron (a region of the thorax) into halves. Larvae can also be identified by physical examination. Females are often larger than the males, with...
