The Big Question
Where have all the Bees gone? There has been a theory circulating that they are all dying out. Whilst there is certainly an issue with habitat destruction and pesticide use, some believe that the Bees aren't going anywhere at all, they are simply waking up early because Spring is unusually warm.
When the queens wake up from their winter hibernation they produce new queens and then die. This means that a warm Spring can see an unusually high amount of activity but summer, the normal time you would expect to see them, is relatively quite.
So keep an eye out for the Bees in Spring but it's probably a good idea to cut down on pesticides anyway and provide good habitats for the bees to make colonies. After all Bees are good for the environment and help pollinate plants - it would make sense not to put obstacles in their way.
