The aim of this note was to record for the first time the finding of Hemilucilia segmentaria
acting as biological vector of Dermatobia hominis, during a study of the diversity of Calliphoridae at Reserva Biológica do Tinguá, Rio de Janeiro, Brazil. The insects were captured using traps baited with chicken vicera, for a period of 28-30 h twice per month. In the period of one year, 1987 insects were collected, 7.5% of which belonged to the H. segmentaria
; of these a female was captured in May 2001, carrying a mass of 20 eggs on the left side of its abdomen.
