Brett Smith for redOrbit.com - Your Universe Online German researchers have uncovered another cautionary tale about the importation of a species that quickly becomes an invasive threat. Introduced to Europe and North America for the purpose of controlling pesky greenhouse aphids, the Asian lady beetle escaped into the ecosystem and quickly dominated the local ladybug population. According to a new report in the journal Science, the aggressive ladybug´s dominance is being assisted...

An alien predator in Europe is leading to a rapid decline of a native ladybugs in Britain, Belgium and Switzerland. Scientists have found that Harlequin ladybugs are overwhelming native ladybugs through predation and competition. The native ladybug, most known for the 2-spots on its back, have declined by 30 percent in Belgium and 44 percent in Britain over the past five years after the Harlequin species arrived in 2001.

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...

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...
