The Hive…

Social Insects10,000 – 60,000 bees per hiveONE queenWorkers

All Female – perform colony maintenance

DronesMales – only purpose is to reproduce

The Queen…

Produced in 2 occasions: Swarming, and SupersedureSwarming is splitting of the hiveSupersedure is when the queen may be failing and the workers elect to rear a new queenQueens mate with many males, but only at the beginning of her life

What if there is more than 1 Queen??

Often more than 1 queen is rearedThe first hatched communicates with the others by “toots” and “quacks”

Emerged queen toots, queen in cell quacksQueen bee pipping

Queens can kill other queens in cellsQueens that meet will fight to the death using stingsSometimes queens will leave with a secondary swarm

How do the bees communicate?

Pheromones! Used in the hive and while foragingAll stages produce pheromones
