Abstract
Insects from a stream at Mont St. Hilaire, Quebec, were sampled monthly for 1 year. The degree of ecological difference between congeneric species in three orders was assessed by using a "coefficient of separation", similar to a modified Jaccard coefficient. It was found that species differed most in their season of occurrence, least in the substrates they occupied. The significance of this result in terms of the avoidance of competition is considered.
