pulling out part of the bee's abdomen when she flies away. As a result, the bee dies. Bees with barbed stingers can often sting other insects without harming themselves. Queen honeybees and bees of many other species, including bumblebees and many solitary bees, have smooth stingers and ca...
However, because the wings of a Gronckle beat at a speed similar to those of hummingbirds, dragonflies, or bees, it is possible for one to sustain flight. In fact, a Gronckle can fly backward, sideways, and even hover in place. However, due to their massive weight and small wings ...
Body:Female bumblebees have a stinger and a pointed abdomen, while males do not have a stinger and have a rounded abdomen. They differ fromcarpenter bees, which have a solid black, shiny and hairless abdomen. Habitat While various bumblebee species may choose different nest sites, they usuall...

The bees around her can feel this air movement. The ones directly behind her, where the air movement is greatest, get a clear idea of where to fly and how far to travel. Once they reach the described position, they begin flying in a search pattern until they find the food source. ...
"Engineers say they can prove that a bumblebee can't fly," said Michael Dickinson, a biologist at the University of California, Berkeley. "And if you apply the theory of fixed wing aircraft to insects, you do calculate that they can't fly. You have to use something different." Dickinson...
Reports on the findings of entomologists Regula Schmid-Hempel and Christine Muller on the effect of parasitic fly on bumble bee behavior. Claim of the entomologists that bees with parasites tend to spe...
Sometimes, small things make a huge impact. After studying how bees in urban environments can survive by navigating small land patches, ecologist Amanda Schochet was inspired to build MICRO, a network of portable science museums the size of vending machi
