World Of Fairyflies Has A New Representative: Tinkerbella Nana
2013-04-24 13:35:49

Pensoft Publishers Mymaridae, commonly known as fairyflies, are one of about 18 families of chalcid wasps. Fairyflies occur worldwide, except in Antarctica. They include the world's smallest known winged insect - Kikiki huna, the body length of which is only 155 μm, and the smallest known adult insect — the wingless male of Dicopomorpha echmepterygis which is only 130 μm. Although fairyflies are among the most common chalcid wasps, they are seldomly...

Ant Family Tree Highlights Importance Of Tropics
2013-04-22 13:39:39

Brett Smith for redOrbit.com - Your Universe Online Scientists currently have two prevailing theories about the high degree of biodiversity in the areas around the tropics: some believe that climate acts as a “museum,” allowing older lineages to persist through time. Others, however, see the tropics as a “cradle,” where new species are able to germinate and thrive. According to a new report in the journal Evolution, a pair of American researchers now says that...

Tracking Study Discovers Ants Change Careers As They Age
2013-04-22 09:29:39

Lawrence LeBlond for redOrbit.com - Your Universe Online A single ant colony can have thousands of ants, all scurrying around performing various tasks, maintaining their territory for the queen. And because they all look alike, studying them individually by eye can prove extremely difficult, if not impossible. To bypass this obstacle, Danielle Mersch and colleagues from the University of Lausanne tagged every single worker in entire ant colonies and tracked them by computer. The...

Scientists at The University of Manchester have found evidence of the genetic basis of the evolutionary arms-race between parasitoids and their aphid hosts. The researchers studied the reaction of aphids when a parasitic wasp with genetic variation laid eggs in them. They found that different genotypes of the wasp affected where the aphids went to die, including whether they left the plant host entirely. The team also found an example of the emergence of a shared phenotype that was partly...

Robot Ants Learn To Navigate A Maze
2013-03-29 10:50:18

Michael Harper for redOrbit.com — Your Universe Online It´s commonly known that ants navigate by scent. As each ant randomly wanders in search for food or shelter, it leaves behind a trail of pheromones which other ants will then follow. The result is that famous line of ants leading to a family picnic or a particularly sticky spill. Though this behavior has been observed for centuries, it´s something which Simon Garnier from the New Jersey Institute of Technology and...

Rare Sawfly Is Host To Peculiar Parasitoid Wasp
2013-03-25 11:28:01

Pensoft Publishers A mysterious parasitoid wasp was found in the Böhmerwald (Northeast Austria) and reared in the garden of the amateur entomologist Ewald Altenhofer of Gross Gerungs municipality, Austria. The parasitoid was identified by Kees van Achterberg, senior researcher at the Naturalis Biodiversity Center in Leiden, the Netherlands, as the rare Seleucus cuneiformis. It is the first time that a tip of its biology was discovered. The study was published in the open...

New Wasp Species Found In 1930s Field Box
2013-03-19 04:49:57

April Flowers for redOrbit.com - Your Universe Online A new study from Dr. Simon van Noort, from Natural History Department, Iziko South African Museum, and Dr. Matthew L. Buffington from the Systematic Entomology Lab, USDA describes nine new species of extremely rare Mayrellinid wasps. Mayrellinids are under-represented in museum collections with most species being known from only a single specimen. There are two genera in the Mayrellinae subfamily, Kiefferiella and Paramblynotus. Only...

Social Bees Use Chemical Signals To Mark Dangerous Flowers
2013-03-14 13:32:43

FECYT - Spanish Foundation for Science and Technology Scientists already knew that some social bee species warn their conspecifics when detecting the presence of a predator near their hive, which in turn causes an attack response to the possible predator. Researchers at the University of Tours (France) in collaboration with the Experimental Station of Arid Zones of Almeria (Spain) have now demonstrated that they also use chemical signals to mark those flowers where they have previously...

New research delivers a sting in the tail for queen wasps. Scientists have sequenced the active parts of the genome — or transcriptome — of primitively eusocial wasps to identify the part of the genome that makes you a queen or a worker. Their work, published in BioMed Central's open access journal Genome Biology, shows that workers have a more active transcriptome than queens. This suggests that in these simple societies, workers may be the 'jack-of-all-trades' in the colony -...

Fruit Flies Force Their Young To Get Liquored-up For Their Own Good
2013-02-22 10:59:06

Emory University When fruit flies sense parasitic wasps in their environment, they lay their eggs in an alcohol-soaked environment, essentially forcing their larvae to consume booze as a drug to combat the deadly wasps. The discovery by biologists at Emory University is being published in the journal Science on Friday, February 22. “The adult flies actually anticipate an infection risk to their children, and then they medicate them by depositing them in alcohol,” says...

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...
