Abstract The distribution of third-stage D. roemeri in its tabanid intermediate host was observed in histological sections of naturally infected Dasybasis oculata and Tabanus parvicallosus. Larvae invade the brain, eye, nerve cord, muscles of the mouthparts, horizontal and indirect flight muscles, fat body, hind gut and gonad of flies. Third-stage D. roemeri migrate from the abdomen via the haemocoelic spaces of the thorax to the head of the fly. Evidence suggests that larvae escape from the intermediate host by rupturing the tip of the labrum or the labro-epipharyngeal membranes. Injury was observed in the eye, nerve cord and musculature. There was no evidence that the parasite had a detrimental effect on the host and tabanids showed no response to the presence of filarioids. Species of Dasybasis and Tabanus acting as intermediate host of D. roemeri in nature epitomize the concept of a 'good' host.
