Grooming is an important behavior for insects. It keeps them clean by removing dirt, fungi and other harmful microorganisms from their bodies. For most insects, such as cockroaches and house flies, grooming is strictly do-it-yourself.
For social insects, such as termites, it's cooperative - workers groom other workers, workers groom soldiers and workers groom the reproductives (including the queen). Grooming is done with the mandibles, basically by gently "chewing" over the body surface of a nestmate. Sometimes, however, it is a little more enthusiastic than gentle (probably the rookies), and body parts get bitten off! So, life in the colony can be a little difficult for the average worker, depending on who groomed you last. Workers may be missing parts of their antennae (easy to nibble off), a leg or part of a wing pad.
