Worker insects are those within social insect colonies (bees, ants, wasps and termites) that are not capable of reproducing.

These workers perform most of the tasks within the colony, such as:

Workers forego their own reproduction to help raise their siblings. It is thought that they do this because they are actually more closely related genetically to their sisters than they would be to their own offspring. Workers often share up to 75% of their genes with the Queen but would only share 50% of its genes with its own offspring.
