The oviposition behavior and development time of Brachymeria villoso (Oliver, 1790) on Trypoxylon albitarse Fabricius, 1804 (Sphecidae) is reported. The parasitism occurs through a little hole made by the parasitoid female in the host nest wall. This hole is used by the parasitoid offspring after its emergence to left the host nest. The parasitoid egg is laid on the host larva before it built its cocoon, when such structure is made the parasitoid egg hatch into a larva that feeds on the living host larva and the parasitoid growth enclosed in the host cocoon without build its own. The development time of B. villosa was 65 days. From two nest of T. albitarse were reared 12 females and one male of B. villosa.
