The Fresno, California Sheriff's Department raided a "beehive chop shop" and uncovered $1m worth of bees stolen in "great beehive heists" that have taken place across the bee-starved state. Read the rest
Japanese researchers demonstrated how a tiny remote-controlled drone could help bees pollinate flowers in areas where bees populations have been reduced due to pesticides, climate change, and other factors. Eijiro Myako and his colleagues at the Japan’s National Institute of Advanced Industrial Science and Technology hope that eventually robotic bees could handle their share of the work autonomously. From New Scientist:
The manually controlled drone is 4 centimetres wide and weighs 15 grams. The bottom is covered in horsehair coated in a special sticky gel. When the drone flies onto a flower, pollen grains stick lightly to the gel, then rub off on the next flower visited.
In experiments, the drone was able to cross-pollinate Japanese lilies (Lilium japonicum). Moreover, the soft, flexible animal hairs did not damage the stamens or pistils when the drone landed on the flowers...
“We hope this will help to counter the problem of bee declines,” says Miyako. “But importantly, bees and drones should be used together.”
Reuters reports that the U.S. Fish and Wildlife Service proposes listing the rusty patched bumble bee among America's endangered species.
Though just one of many species of bumble bee, Bombus affinis's sharp decline is a worry to conservationists. About a quarter of bumble bee species face "a risk of extinction."

The agency attributes the decline to a number of factors, including disease, pesticides, climate change and habitat loss.
Bumble bees, as distinguished from domesticated honey bees, are essential pollinators of wildflowers and about a third of U.S. crops, from blueberries to tomatoes, said Sarina Jepsen of the Xerces Society for Invertebrate Conservation, which petitioned the government for protection of the insect.
Bumble bees’ annual economic value to farms is estimated at $3.5 billion, according to experts.
New research shows that bees can recognize flowers by the plants' tiny electric field that differs between species. The electric field bends the tiny hairs on a bee's body, firing neurons located at the base of the hair. From the journal Science:
Such fields—which form from the imbalance of charge between the ground and the atmosphere—are unique to each species, based on the plant’s distance from the ground and shape. Flowers use them as an additional way to advertise themselves to pollinators...
Electric fields can only be sensed from a distance of 10 cm or so, so they’re not very useful for large animals like ourselves. But for small insects, this distance represents several body lengths, a relatively long distance.

From the Independent:
They found that in both, consciousness appeared to be associated with the “midbrain”. That part of the brain is the ancient core of the brain, which supports awareness for us and apparently for insects, too.
Though insects have tiny brains, they appear to serve the same function that the midbrain does for humans. They are able to tie together memory, perception and other key parts of consciousness, and use it to decide what to do - which is the same function that human’s brains do.

“Bees are known to perform very complex tasks considering the size of their brains and their simplicity compared to high-level organisms,” said Gill. “If we can focus on simple tissues and find the small changes that can have profound effects on behavior, it can give us a basis to start understanding how very small changes to that brain can do that.”Read the rest
"One month a year, giant Himalayan bees, the biggest bees in the world, come to collect nectar from a poisonous flower, giving the honey they make certain medicinal, aphrodisiac, and hallucinogenic properties."
In this short documentary, filmmaker Raphael Treza meets with a Nepalese tribe to learn about this honey, and how they use it. During the making of the film, the translator eats too much of the honey and falls unconscious.
