    Some ecological aspects of corixids in San Miguel Arco Reservoir, State of México are analyzed during two seasons of year 2005 (Winter and Spring). Five littoral sampling stations were located and in each one, were measured: depth, transparency, temperature, oxygen, pH, conductivity, hardness and alkalinity. The corixids were captured with spoon net of 50 x 30 cm of frame. Also, it were considered the abundance, Shannon-Wiener diversity, Importance Value Index and dissimilitude analysis. Three species were recorded that in descending order of abundance were: Trichocorixella mexicana Hungerford, 1927; Graptocorixa abominalis, Say, 1832 and Krizousacorixa femorata, Guerín, 1857; in both seasons. In Winter the greater abundance was recorded in station V (104 orgs.·m-2) and the one of minor in station I (20 orgs.·m-2). In Spring the abundance was greater in station IV (37 orgs.·m-2) and minor in station II ( 8 orgs.·m-2). The diversity was greater in station III at both seasons (1.34 y 1.18 bits por ind.); whereas the smaller diversity was recorder in station V in Winter (0.91) and station II in Spring (0.000008). The importance value was greater for T. mexicana at the two seasons (100.59 and 100.48) and minor for K. femorata in both samplings (60.02 and 20.01). The dissimilitude analysis showed remarkable differences between the sampling stations at both seasons. The conclusion was that the variations in the abundance of corixids are based on the variations of the physical and chemical parameters, even though these are not very considerable.
