      Comparative biology of the wormDichogaster bolaui (Michaelsen) in a pasture and compost pit has been reported. Important findings are: (i) restriction of more than 84% ofDichogaster bolaui population to upper 10 cm of the soil depth indicating surface living habit; (ii) attainment of a peak population of 12617 worms/m2; (iii) a zero population during summer revealing environmental drasticity (soil temperature > 31°C, soil moisture < 1 g%) and yearly recolonisation of worms; (iv) habitat variation in the reproductive strategy with an unimodality in pasture and bimodality in compost pit; and (v) preemergence of juveniles followed by post cocoon peak indicating population survival through cocoons during summer.
