Behaviour

Wohlfahrtia magnifica is a species for which, with regard to its behaviour in the field, we know relatively little. 

Adult males will sit on raised objects in the environment, called mating stations (for example, large stones and logs), from where they will fly out to mate with passing females. They will actually intercept almost any passing fly of approximately the same size as a female, but will only actively engage with those of the right sex and species, recognised by cuticular pheromones.

Very little is known of female behaviour other than their activity around potential host animals. They can be attracted to even healthy hosts, depositing live larvae at the body orifices, especially genitalia, but already infested hosts are most attractive (Hall et al., 1995).

Migration

There is no known regular migration of this species but it is subject to range extensions either naturally or through the assistance of humans, for example with movements of infested livestock.

In 1999 it reached Crete, Greece, for the first time and has now spread throughout the island (Sotiraki et al, 2003)
