(2005) described the immature stages and male from specimens collected in Buenos Aires province. The identification of Philornis species is difficult because the general morphological similarity exhibited by the species of this genus and the intra-specific variation of some characters (Couri et al . 2009). Biology . The larvae of this species are subcutaneous parasite of several birds ( e.g. , Furnariidae , Icteridae , Mimidae , Troglodytidae , and Tyrannidae ) ( Turienzo & Di Iorio 2007 ).
