Fact of the day

Bees (and other Hymenoptera, such as wasps and ants) are haplodiploid.

This means that the sex of a larvae is determined by whether or not the egg it hatches from is fertilised. If an egg remains unfertilised, the offspring from it will be male; if it is fertilised, the offspring will be female. Thus male bees have no father and no sons

This is awesome! Self-regulating system to keep the sexes balanced.
