Biology: In Brazil, this is a relatively common species, with populational peaks from September to December, and showing synathropic habits (Linhares 1981; Dias et al. 1984b; Mendes & Linhares 1993). This species also showed preference for faeces baits (Ferreira 1979; Linhares 1981; Dias et al. 1984c). Furthermore, O. terminalis was listed as coprophagous, reared in cattle dung (Marchiori et al. 2001; Mendes & Linhares 2002) or human faeces (Mendes & Linhares 1993).
