The paper deals with the findings on some aspect of ecology ofSchizodactylus monstrosus Drury. Studies on vertical distribution showed that the highest total density was in the 0 to 20 cm depth. Maximum concentration of the species was found in the first horizontal row. Monthly population structure on vertical distribution was also studied. Statistical analysis showed a significant correlation between the relative humidity and the distribution. Biomass of both the sexes and nymphal populated was estimated.
