Bees in the real world have a very different biology than the bees in this movie. In the real world, male bees don't contribute at all to the honey-making process, which is done entirely by females. Male bees are drones, and just hang around the hive to mate with the queen. Drones have no stingers - that's the female reproductive organ and self-defense method - though bees do tend to die after stinging, as the stinger (which has tiny barbs on it) rips free of the body as the bee flies away. Also, male mosquitoes do not drink blood, only female mosquitoes do, as a protein source for their eggs, not as sustenance for themselves. Furthermore, insects have 6 legs, not 4. They have compound eyes, not simple ones. Lastly, they do not have fingers, teeth, clothing or the ability to mimic human speech.
