Show or Tell? Testing Peacock Spiders’ Multi-Modal Mating Display
Famous for their flashy colors, peacock spiders also emit vibrational signals during their mating dance. But why both kinds of courtship cues? And which kind matters more? Researchers have been studying peacock spiders to find out.
When Cicada-Killer Wasps Become Cicada-Stealer Wasps
Hunting cicadas and lugging them back to a nest is hard work for a cicada-killer wasp. But sometimes all that hard work goes to waste, when a fellow wasp swoops in and lays her egg on the other wasp's prey. And that's if the cicada isn't stolen by a bird first.
Balance, Hearing, and More: Why Some Wasps Have Fat Lower Legs
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.
Fossilized Insect Discovered Not in Amber, But in Opal
An opal discovered in Indonesia exhibits a rare inclusion: a preserved insect embedded within.
So Many Shot Hole Borers: New Research Charts Four Nearly Identical Species
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.
How Insects Inspire the Look of Sci-Fi and Fantasy Films
Some insects look like science-fiction stars precisely because the creative minds behind popular entertainment look to insects to spark their imagination.
Need to Mail Mosquitoes? Pack Them Up Nice and Snug
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.
Tabloid Sensationalism Aside, Lady Bugs Are Still Fascinating
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.
Cuckoo Bumble Bees: What We Can Learn From Their Cheating Ways (If They Don’t Go Extinct First)
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.
The Best Look Yet at the Tiny Fungus Storage Units Inside Ambrosia Beetles
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.
Bees Stopped Buzzing During the 2017 Total Solar Eclipse
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.
Busy Bees: An Up-Close Look at One Bee Species’ Scramble to Mate
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.
Butterfly Pupae Make Sounds In Never-Before-Known Ways
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.
A Night With the Synchronous Fireflies in the Great Smoky Mountains
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.

Meddling in the Mutualism: Fly Larva Uses Nectar to Lure Ants for Lunch
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.
