You might not have seen many of these little guys around lately.
Environmentalists have found that there has been around a massive 85 percent drop in the numbers of Queen bees in the UK.
They think that the pesticides, chemicals used on farms and gardens, cause the buzzy creatures to become disorientated so they can't find their way back to their hives.
Numbers of bees have been going down for the last decade.
Bees play a really important role in the environment, they pollinate loads of flower, fruit and other plants that we rely on.
In fact all their hard work is thought to be worth a whopping £430 million to the UK economy.
