Research entomologist Louis Hesler takes readers along as he and others search for types of ladybugs that were once common but have become extremely rare in eastern North America I was frustrated. I had been searching for years for the so-called "lost ladybugs," but hadn't found any. It was 2008, and only a few had been found by anyone in the last three decades, although they were once common in many areas, especially crop fields such as wheat and alfalfa. There are actually hundreds of kinds...

University of Montreal researcher studies odd insect behavior Are ladybugs being overtaken by wasps? A Universit© de Montr©al entomologist is investigating a type of wasp (Dinocampus coccinellae) present in Quebec that forces ladybugs (Coccinella maculata) to carry their larvae. These wasps lay their eggs on the ladybug's body, a common practice in the insect world, yet they don't kill their host. "What is fascinating is that the ladybug is partially paralyzed by the parasite, yet...

Swarms of ladybugs are causing problems for many Americans this season, and even pest control workers are not immune to being bugged. "Every night when I get home and it's dark, I turn on the lights and I have them to greet me. A lot of them," Gene Scholes, entomologist for Reliable Pest Solutions in Quincy, Illinois, told the Associated Press. Scholes uses his household vacuum cleaner to eliminate the massive ladybug swarms. Experts claim that ladybugs form larger swarms on warm days after...

Researchers in New York are breeding colonies of ladybugs from those found by scientists in Oregon and Colorado during a year-long search. Last year, entomologist John Losey from Cornell University first introduced the Lost Ladybug Project in an attempt to find out why the once-common native ladybug species had almost completely disappeared across the nation. The project, which is funded by the National Science Foundation, rounds up citizen scientists, or individual volunteers who may have...

Scientists have warned that the Harlequin ladybird is putting over 1,000 species in the UK in peril, BBC News reported. Dr. Helen Roy of the Center for Ecology and Hydrology called the rate of spread "dramatic and unprecedented." In just four years, the ladybird has spread to most parts of the UK, where it feeds on many other insects. But the Royal Society's Summer Science Exhibition produced research that suggests local ladybird parasites are adapting to prey on the interloper. Scientists...

Spanish researchers say ladybugs in olive orchards are a good indicator of the groves' health and sustainability. The University of Granada found that ladybugs are a useful way of distinguishing organic, conventional and integrated farming systems. The university said a two-year study of three large Spanish olive groves showed the richness and abundance of ladybugs was higher in organic orchards.

Utah researchers said bark beetles are destroying spruce trees in the Dixie National Forest. The U.S. Forest Service's Bark Beetle Technical Working Group said the bark beetle is an "agent of change" in conifer forests in the Rocky Mountain region, the Deseret Morning News reported this week. "We're talking hundreds of thousands of acres they have basically been wiped out -- pretty much the entire spruce component in the Dixie National Forest," Colleen Keyes of the Utah Division of...

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...

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...

The Asian long-horned beetle (Anoplophora glabripennis) is native to China and Korea where it causes widespread destruction of poplar, willow, elm, and maple throughout vast areas of eastern Asia. Asian longhorned beetles are big, showy insects: shiny and coal black with white spots. Adults are about 1 inch (2.5 cm) long. On their head is a pair of very long antennae that are alternately ringed in black and white. The antennae are longer than the insect's body. An invasive species in...

In the eastern U.S. and Canada, the Bessbug (Passalidae) is a very large beetle measuring roughly 1 inch (2.5 cm) both as an adult and a larva, that feeds on rotting wood. It has a "horn" on the dorsal head. They are highly subsocial beetles that care for the young; they prepare food for them and help the larvae construct the pupal case. Fourteen acoustical signals are known for the family, more than many vertebrates. Adults produce sound by rubbing the upper surface of the abdomen against...

Cucujiformia is an infraorder of Polyphagan beetles, representing the vast majority of plant eating beetles. The infraorder contains six superfamilies: Lymexylidae (ship-timber beetles) Cleroidea (checkered beetles, bark-gnawing beetles and soft winged flower beetles) Cucujoidea (31 families that includes ladybirds, fungus beetles and bark beetles) Tenebrionoidea (also Heteromera) (30 families including blister beetles and ant-like beetles) Chrysomeloidea (4 families including...

The soldier beetles (Cantharidae) are relatively soft-bodied, straight-sided beetles. They are closely related to the Lampyridae, or firefly family. Some are important predators of aphids during their brief adulthood.
