Host–parasite systems are characterised by coevolutionary arms races between host and parasite. Parasites are often the driving force, as they replicate much faster than their hosts and have shorter generation times and larger population sizes, resulting in higher mutation rates per time interval.

Cuckoo bumblebees (subgenus Psithyrus) are social parasites in colonies of their host bumblebee species (Bombus). In spring, parasitic females awaken from hibernation and start searching for established host nests. Some Psithyrus species are specialized on one host species, whereas generalists parasitize several species.

Homing ability of the bumblebee, Bombus terrestris [PDF]
, 2008 The ability of bumblebees to locate their nest site following artificial displacement was investigated. Bombus terrestris (Hymenoptera: Apidae) workers were marked with numbered tags and displaced up to 15 km from their nest. Bees returned from distances of up to 9.8 km, with the proportion of bees returning declining with distance of the release site ...
