ResumoPhilornis is a neotropical genus of muscid fly that interacts with birds and may affect the development and survival of the birds' offspring. Although Philornis is a relatively common parasite, there is a lack of information about Philornis hosts in several parts of the Americas. In this study, two nests of the Rufousfronted Thornbird ( Phacellodomus rufifrons) were collected in Pedro Leopoldo, southeast Brazil. The first contained four nestlings of advanced age (about 20 d old) and a recently emerged Philornis torquans female adult fly. The second nest contained three nestlings (less than 7 d old) and several Philornis torquans subcutaneous larvae. One of the nestlings was infested by 53 larvae, which had attacked several parts of its body and caused individual wounds containing 1 to more than 15 larvae. The length of the larvae ranged from 3 to 18 mm and only one was a second instar; the remaining 69 were third instars. The pupal period lasted 9-13 d. In total, 71 larvae were collected from the nest, with nestling parasitism varying from 7 to 53 larvae (mean- 23.7±25.5 larvae/nestling).
