Aspect Diversity in Moths: A Temperate-Tropical Comparison

Abstract

The appearance of resting moths in one tropical and two temperate localities was described by twelve characters and analyzed by numerical taxonomic techniques to determine similiarities between species in each sample. The average similarity between nearest neighbors was found to be nearly identical in the three samples. We interpret this result as suggesting that predation acts to limit the similarity of appearance in different moth communities at a similar level. Differences in species diversity between areas are reflected in differences in the variety of appearances used by moths, and presumably in the variety of their resting backgrounds, rather than in the density of species packing within an abstract, morphologically defined aspect space.
