Microhabitat selection plays a major role in the ecology populations and that it is important for the survival and population dynamics. The aim of this work is to describe the use of micro-habitat for O. occidentalis. We recorded the location of individuals for random walks and measure the following variables: type of substrate (water, soil or vegetation). Distance to nearest vegetation (10-49cm, 50-99cm, 100-200cm, > 200 cm); height of the nearest vegetation ( 150); distance to water (in the water, 100cm, 101-200cm,> 200 cm). We analyzed data from 127 individuals. The 71.6% used the substrate water during all study period (χ2 = 49.4 df = 2 p
