A new study suggests that jewel scarab beetles find each other"”and hide from their enemies"”using the same technology that creates the 3D effects for the blockbuster movie Avatar. According to researchers from the University of Texas, the jewel scarab species Chrysina gloriosa can distinguish between circularly polarized and unpolarized light. That ability could provide the beetles with a tremendous advantage, the researchers say, because most of the light reflected off these...

Following months of gruelling tests and trials, scientists now reveal the World's strongest insect to be a species of dung beetle called Onthophagus taurus. In an experiment to find out why animals vary so much in strength and endurance, Dr Rob Knell from Queen Mary, University of London and Professor Leigh Simmons from the University of Western Australia found the strongest beetle could pull an astonishing 1,141 times its own body weight - the equivalent of a 70kg person lifting 80 tonnes...

Geraniums may hold the key to controlling the devastating Japanese beetle, which feeds on nearly 300 plant species and costs the ornamental plant industry $450 million in damage each year, according to scientists with the Agricultural Research Service (ARS). The beetle, Popillia japonica Newman, can feast on a wide variety of plants, including ornamentals, soybean, maize, fruits and vegetables. But within 30 minutes of consuming geranium petals, the beetle rolls over on its back, its legs...

A new study of 30 million year old fossil 'mega-dung' from extinct giant South American mammals reveals evidence of complex ecological interactions and theft of dung-beetles' food stores by other animals.The dung-beetle has fallen on hard times. Once worshiped by the Ancient Egyptians its status has now slipped to that of unsung and forgotten hero, the butt of scatological jokes. Yet the dung-beetle is truly heroic. It is a well known 'fact' that were it not for the dung-beetle the world...

The evolutionary tradeoff between becoming a bigger fighter or lover could lead to new species among dung beetle populations. Male beetles may not transform in the blink of an eye, but natural selection seems to have driven rapid evolution in the size of their fighting horns - and their reproductive tools - during a time period of just 50 years in one newly studied case. "As horns get bigger, copulatory organs get smaller, or vice versa," said Armin Moczek, an evolutionary...

By Chris Kick Q: My trees are getting eaten up by Japanese beetles. What should I do? A: Japanese beetles have definitely made themselves known this past week. But do not put out beetle traps. Research has shown that, despite the number of beetles the traps catch, they actually bring more of them into the area where they are placed. If you do want to use traps, place them away from any plants you want to protect. If the trees are not too big, hand picking them and putting them into soapy...

By TOWN AND COUNTRY GERALD MAHAN Interest continues to grow in ways of making agriculture more sustainable. Emphasis is placed on practices like cover crops, grassfed livestock, organic dairy, community supported agriculture, pasture- raised poultry and beneficial insect production to name a few. Several farm tours and workshops are offered June-October through efforts of Innovative Farmers of Ohio, USA-NRCS, Ohio Ecological Food and Farm Association, Ohio Forage and...

In the beetle world, it's the big guys who often win in the mating game, chomping their larger jaws down on the competition to fend them off. But biggest is not always best. All sizes of male sap beetles - large, medium and small - can get lucky. Each size adopts a different tactic in finding a mate, evolutionary ecologist Takahisa Miyatake at Okayama University in Japan and his colleagues found. These beetles are found all throughout Japan. They live off the sap exuding from...

The creature's "Ëœpulling techniques' will be revealed in the April edition of the Royal Entomological Society's Ecological Entomology journal.In the world of armed beetles, biggest is usually best, as males often fight for mating rights and those with the largest jaws beat off the competition. However, this is not always the case with one particular species.Researchers at Okayama University in Japan have been monitoring the mating habits of large, medium and small Librodor...

The South American Scarab Dung Beetle (Oxysternon conspicillatum) is a species of dung beetle of the superfamily Scarabaeoidea. Most Scarab beetles are known as true dung beetles as they feed mainly on feces. Dung beetles live in many different habitats, including desert, farmland, forest, and grasslands. They do not like extremely cold or dry weather. This beetle species is trimorphic (able to produce up to three different types of males). Each male has different forms of body weaponry...

PHOTO CAPTION: Goliath Beetle Beetles are one of the main groups of insects. Their order, Coleoptera (meaning "sheathed wing"), has more species than any other order in the entire animal kingdom. Forty percent of all described insect species are beetles (about 350,000 species), and new species are regularly discovered. Estimates put the total number of species at between 5 and 8 million. When J. B. S. Haldane, a British geneticist, was asked what his studies of nature revealed about...

The Japanese Beetle (Popillia japonica) is a beetle about 0.6 inches (1.5 cm) long and 0.4 inches (1 cm) wide (smaller in Canada), with shiny copper-colored elytra and a shiny green top of the thorax and head. Although it is not very destructive in Japan, where it is controlled by natural enemies, in America it is a serious pest to rose bushes and other plants. It is a weak flyer and drops several centimeters when it hits a wall. Japanese Beetle traps therefore consist of a pair of crossed...
