Parasitic use of chemical mimicry involves the invasion of the nest of a duped species, which may consist of an individual or a colony. By emitting mimics of the chemicals that create the host's familiar odours the invader is able to conceal themselves efficiently within the nest without alerting the host.
One example of a group of insects that uses this method of chemical mimicry would be cuckoo bees (genus: Nomada). Cuckoo bees will parasitize bees of the families Melittidae and Andrenidae. Cuckoo bee males will produce chemicals that are similar in structure to the volatile lipids secreted by host females and these chemicals are transferred to cuckoo females so that they may camouflage their eggs within the host's nest. This would allow the females to pass off the care of her eggs and larvae onto the host, benefiting the parasite and burdening the host.
