Rare species are often ignore in many ecological studies for several reasons which include the apparent difficulty in analysis and the fact that many ecologists do not consider such species important in understanding community structure. In reality the world's biota consists mostly of rare species with common species the deviation. In the current paper we examine the spatial distribution of rare stream insects to determine if their mean distances among habitats is clumped, over-disperse or random. We also examined stream conditions to determine if sites that harbor rare species are different from sites in which rare species were not found.
