South African worker honeybees reproduce by making near-perfect clones of themselves

A team of researchers from the University of Sydney, the ARC-Plant Protection Research Institute and York University, has found that workers in a species of honeybee found in South Africa reproduce by making near-perfect clones of themselves. In their paper published in Proceedings of the Roy

Researchers Use Radar to Uncover Mystery of Honeybee Mating Behaviors

Scientists from Queen Mary University of London and Rothamsted Research have used radar technology to track male honeybees called drones, and reveal the secrets of their mating behaviors. The study, published in the latest issue of the iScience journal, suggests that male bees swarm together in s

Bees can tell time by temperature, research finds

Bees are known to tell time by light and social cues. Now, postdoctoral scholar in biological sciences Manuel Giannoni-Guzmán and researchers from Brandeis University, University of Puerto Rico Rio Piedras, University of Pittsburgh and East Tennessee State University have shown that the cir

Surprising sand fly find yields new species of bacteria

Researchers at North Carolina State University and the University of North Carolina Greensboro made a surprising finding while examining areas where sand flies rear their young: a new species of bacteria that is highly attractive to pregnant, or gravid, sand flies. The findings could advance the p

Flies grow bigger up north: Insect size a promising new proxy for palaeoclimate

Scientists use many proxies to reconstruct Earth's ancient climates. Pollen, diatoms, geochemical isotopes and fossils, for example, all contribute to piecing together past-climate puzzles. The ubiquity and wide geographic range of insects—like the nonbiting midge (Order Diptera, Family Chir

Tarantula's ubiquity traced back to the cretaceous

Tarantulas are among the most notorious spiders, due in part to their size, vibrant colors and prevalence throughout the world. But one thing most people don't know is that tarantulas are homebodies. Females and their young rarely leave their burrows and only mature males will wander to seek out a

Social wasps lose face recognition abilities in isolation

Just as humans are challenged from the social isolation caused by the coronavirus pandemic, a new study finds that a solitary lifestyle has profound effects on the brains of a social insect: paper wasps.   Paper wasps (Polistes fuscatus) recognize the brightly colored faces of

Fireflies have a potential—protective 'musical armor' against bats

A new study at Tel Aviv University reveals a possible defense mechanism developed by fireflies for protection against bats that might prey on them. According to the study, fireflies produce strong ultrasonic sounds—soundwaves that the human ear, and more importantly the fireflies themselves,

Population of Mexico's monarch butterflies falls 26%, conservationists find

The population of monarch butterflies that arrived in Mexico’s forests to hibernate this winter fell 26% from a year earlier, the country’s Commission for National Protected Areas and the World Wildlife Fund (WWF) said on Thursday. Millions of orange and black monarch butterflies migr

New mutations in malaria parasite encourage resistance against key preventive drug

A male Springbok praying mantis looking for a hook up doesn't have to worry about a female stealing his heart away.   There is, however, a very good change she'll bite his head off, and he knows it. Indeed, 60 percent of sexual encounters between Springboks—one of nearl

Genital shape key to male flies' sexual success

Having genitals of a certain shape and size gives male flies a major reproductive advantage, new research shows.   University of Exeter scientists examined the reproductive success of male Drosophila simulans flies both alone with a female and in various states of competition with other mal

New mutations in malaria parasite encourage resistance against key preventive drug

In the ongoing arms race between humans and the parasite that causes malaria, Taane Clark and colleagues at the London School of Hygiene and Tropical Medicine (LSHTM) report that new mutations that enhance resistance to a drug used to prevent malaria in pregnant women and children are already comm

Fleas are Members of Scorpionflies Family, New Study Finds

A study of more than 1,400 protein-coding genes of fleas has resolved one of the longest-standing mysteries by reordering the insect's placement in the tree of life. The University of Bristol study, published in the journal Palaeoentomology, drew on the largest insect molecular dataset available.

Brain gene expression patterns predict behavior of individual honey bees

An unusual study that involved bar coding and tracking the behavior of thousands of individual honey bees in six queenless bee hives and analyzing gene expression in their brains offers new insights into how gene regulation contributes to social behavior.   The study, reported in the jo

Synergy between biotech and classical control tactics rid US of invasive pest

Genetically engineered cotton and classical pest control tactics combined to rid the United States and Northern Mexico of a devastating pest, according to a new study by Agricultural Research Service (ARS) and University of Arizona (UofA) scientists published in the Proceedings of the Nationa

Feds to delay seeking legal protection for monarch butterfly

Federal officials on Tuesday declared the monarch butterfly "a candidate" for threatened or endangered status, but said no action would be taken for several years because of the many other species waiting for that designation.   Environmentalists said delaying that long could spell disa

Young Egyptian deserts degree and finds fortune in scorpions

Several years ago, a young Egyptian man abandoned his degree in archaeology to hunt scorpions in the country's deserts and shores, extracting their venom for medicinal use. At just 25 years old, Mohamed Hamdy Boshta is now the owner of the Cairo Venom Company — a project housing 80,000 scor

Catapulting spider winds up web to launch itself at prey: Study

A study published Monday has found that an arachnid species is capable of winding up its web to store up elastic energy, before releasing its grip and catapulting itself at furious speed toward its unsuspecting prey. The development places the triangle-weaver spider, or Hyptiotes cavatus, alongsi
