Abstract: In the natural distribution of species population, there exist a paradoxial relationship between richness and abundance. The paradox has been investigated in terms of inverse relationship between the species richness & abundance in the population of Bihar hairy caterpillar, Spilosoma spp. surveyed & sampled from urban area of Saharsa district, Bihar. This peculiarity amounts to the logarithmic relationship in the statistical computation of species diversity as per Shannon Wiener equation1.
