	abstract = {The seasonal activity of Onthophagus hirculus Mannerheim in a natural prairie of Uruguay was studied using physiological age- grading techniques. This beetle is a bivoltine species, active from spring to autumn. At 22 degrees C the mean development time from egg to adult was 44 days. Females start laying 25-30 days after emergence. During their lifetime, females lay 4.3 +/- 1.25 eggs (n = 10), each in its respective brood mass. The lifespan of females under laboratory conditions is 74.3 +/- 10.28 days (n = 10).},
