The fat lower legs that dangle below flying wasps in the family Gasteruptiidae turn out to be filled with insect fat body, and they may play key roles in flight dynamics, detecting vibrations from prey, and even detoxification.
An opal discovered in Indonesia exhibits a rare inclusion: a preserved insect embedded within.
Tiny beetles once known as tea shot hole borers are actually a group of four distinct species that appear almost exactly the same to even the trained eye. In a new study, researchers combine both physical measurements and molecular genetics to better define the members of the Euwallacea fornicatus cryptic species complex.
Some insects look like science-fiction stars precisely because the creative minds behind popular entertainment look to insects to spark their imagination.
Several emerging mosquito-management methods require the transport of mosquitoes to precise locations. There, lab-reared mosquitoes—for instance, sterilized males—mix with wild mosquitoes and hinder the population's ability to reproduce or transmit disease. But, getting mosquitoes from lab to wild presents logistical challenges. A team led by researchers at New Mexico State University are tackling this problem and have made a surprising discovery about just how tightly live mosquitoes can be packed up.
Despite headlines to the contrary in British tabloids this fall, harlequin ladybird beetles are not killing off native species by giving them a sexually transmitted fungal infection. "There have been stories mixing up various research findings into quite sensational headlines, which is a shame because these fungi and the ladybirds are fascinating in their own right," says ecological entomologist Helen Roy, Ph.D., of the Centre for Ecology & Hydrology in Wallingford, England.
Learning how cuckoo bumble bees cheat the eusocial system can tell scientists a lot about how insect sociality evolves and how hosts and parasites coevolve. But, as other bees face declines, cuckoo bees will only get more difficult to study.
Advances in microscopic imaging techniques are revealing, in unprecedented detail, the structure of mycangia—the internal organs that ambrosia beetles use to store and transport the symbiotic fungi they farm.
A study conducted during the 2017 total solar eclipse in North America found that bees remained active during partial-eclipse phases, but they essentially ceased flying during totality.
With high-speed, high-definition cameras, researchers at the University of Arizona got an unprecedented look at the mating habits of the solitary bee species Diadasia rinconis and gained new insights into their courtship behaviors and the selective pressures those behaviors produce.
New research explores how pupae of certain butterfly species make a "twittering" noise—via a wiggling movement that triggers sound from tiny structures in the membranes between their abdominal segments.
Pest management pro Pamela Blauvelt recounts a trip with colleagues to witness the annual synchronous fireflies phenomenon at night in Great Smoky Mountains National Park.
Check out the five finalist videos in the Entomological Society of America's 2018 YouTube Your Entomology Contest. Winner, runner-up, and honorable mentions will be announced at Entomology 2018.
In the Brazilian savanna, the larvae of a fruit-fly species exploits an ant-plant mutualism by trapping and preying on ants atop the plant's nectar deposits.
A new study in the Annals of the Entomological Society of America examines how two ant species swim and concludes that bigger is indeed better when it comes to which of them swims fastest.
Ever wondered how one might feed 20 million fly larvae every week? Get a glimpse into the work of entomologists who fine-tune the diet for mass-reared screwworm flies at the Panama – United States Commission for the Eradication and Prevention of Screwworm.
