RESUMO

In Central Amazonia the tabanid Betrequia ocellala Oldroyd, 1970 was recorded for the first time blood feeding on caimans during an experiment in September/October 1996 at Ducke Reserve, Manaus, Brazil. Among different available hosts (Caiman, horse, duck and human) B. ocellata was observed only on Caiman crocodilus (Linnaeus, 1758), suggesting specific blood feeding on crocodilians. The adult flight season, diurnal blood feeding period and flight stratification are presented. Other tabanid species feeding or landing on caimans are also recorded.
