The term ‘phoresis’ derives from the Greek verb ϕέρω (‘phero’) meaning to bear/carry. This association involves one species providing shelter, support, or transport for another organism of a different species and may be temporary or permanent. For example, apart from during their first instar, the larvae, and pupae of the blackfly Simulium neavei attach themselves to the outer surface of freshwater crabs. The larvae feed by filtering out phytoplankton and detritus from the water and the crabs act as a firm yet mobile substrate on which to attach. An appreciation of this association is important because adult S. neavei are vectors of the filarial nematode Onchocerca volvulus that causes ‘River Blindness’.
