A comprehensive study of the transmission of at 4 locations in Guatemala with different prevalence rates of onchocerciasis included observations on potential secondary vectors, the most prevalent of which were , and . Filariae encountered in were primarily of a -like species, but third-stage larvae indistinguishable from were found in 4 flies of this species. Our findings suggest that may occasionally be transmitted by , but such transmission is likely limited to areas having both a high parasite prevalence maintained by and a relatively high host-seeking density of . Two third-stage larvae that could not be differentiated from were found once in ; however, transmission by this species appears to be inconsequential.
