Mating behavior non uniformity of Enallagma ebrium and Enallagma hageni damselflies in two differing habitats.

Two closely related species of damselfly were observed to display different oviposition patterns in two different habitats. The question was raised whether this difference was purely taxonomic, in that one species was behaving one way while the other a different way, or if it reflected a difference in the ecology of the two habitats of the flies instead. Measuring number of species ovipositing by each method as well as some general ecological components in each habitat, I found that the difference in oviposition did not seem to be taxonomic but due to ecological variables. Why these flies behave this way is still in question.http://deepblue.lib.umich.edu/bitstream/2027.42/54578/1/3017.pdfDescription of 3017.pdf : Access restricted to on-site users at the U-M Biological Station
