Biology: Previous works indicate that O. thornax is very abundant, especially during summer and autumn in Brazil, with a wide range of habitat and bait preferences ( Ferreira 1979; Linhares 1981; Dias et al. 1984 a, b, c; Mendes & Linhares 1993). Two natural larviposition habits were alternatively recorded for this species: on faeces or dung (D’Almeida 1988, 1989; Mendes & Linhares 1993; Marchiori et al. 2001; Mendes & Linhares 2002), and on dead fish (D’Almeida 1994).
