Haemagogus janthinomys is found almost exclusively in primary tropical rain forest throughout most of its range and is decidedly arboreal in habit, seldom descending to ground level to bite and then only when the forest canopy has been disturbed. It breeds primarily in treeholes, though it is often taken in bamboo oviposition traps. The treeholes are probably high and inaccessable for in the rain forests of Central America, janthinomys reaches its maximum density at elevations between 100 and 1000 meters. (Arnell 1973:40)

Medical Importance

Because of its ability to harbor and transmit the virus and its arboreal habits, janthinomys is the primary vector in the cycle of sylvan yellow fever which is endemic in several areas in South America. (Arnell 1973:40)
