As gardeners get busy filling tubs and borders with colourful bedding plants, scientists at the Universities of Cambridge and Bristol have discovered more about what makes flowers attractive to bees rather than humans.

Research from North Carolina State University shows that honey bees 'self-medicate' when their colony is infected with a harmful fungus, bringing in increased amounts of antifungal plant resins to ward off the pathogen.

Honeybees don't just communicate with each other through "sign language". They do the same for predators to warn them off. And it works.

This is one of the most succinct and interesting videos I've ever seen about how bees communicate with each other. Using a series of precise dance moves, they inform their hive mates about the locations of food sources.

Bees are a flower's best friends. Echoing previous studies from the northern part of the world, the Australian data, published today in the Proceedings of the Royal Society B, shows that flowers Down Under show the most color variance in the narrow spectra that insects are most sensitive to. This helps an insect distinguish flowers, remember their favorite, and return to it—good news for the plant. The results, now replicated on two continents, likely hold true elsewhere as well.

"Beekeepers would love to get rid of propolis, a sticky substance made of resins that bees use to line their hives, because it makes it hard to pry hives open. But propolis isn’t just gluing the hive together, according to a new study published in PLoS ONE—honeybees use it to fight off fungal infections and seek it out when their hives are infected. Bees invest a lot of effort in hunting down the resins that make up propolis, which they forage from plants, just as they do nectar. That means that every minute a bee is looking for resin is a minute it’s not looking for food. The trade-off is worth it, apparently, because propolis kills bacteria and fungi lurking in the colony."

The video below shows how 30,000 honey bees are killed by just 30 hornets in a few hours. The Japanese Giant Hornets also have particularly strong venom and their sting is said to excruciatingly painful. In fact, over 40 people die every year from anaphylactic shock induced by hornet stings making it the most deadly animal in Japan!

However, specialization of the ant type (though much less extreme) was recently discovered for the first time in a bee species1. The species is Tetragonisca angustula, known to Brazilians as Jataí, and members of the species are small and stingless. The researchers noticed that, given the short 20-day lifespan of an average worker, guards station themselves at the hive entrance for an unusual amount of time. While honeybee workers guard the entrance for only a single day in their sequence of jobs, Jataí guards stay for at least five. Combined with the observation that guards appear larger than foragers (the other, larger group of bees), this led them to hypothesize that guards are a separate caste.

Something is very wrong with the bees. Since 2006, the mysterious phenomenon known as colony collapse disorder has wiped out countless honeybee colonies throughout Europe and North America, and nobody knows why.
