Patch fidelity in coexisting territorial damselfly species, Hetaerina cruentata and Argia extranea was studied to determine if these species displayed differing territorial behavior, which may be one mechanism for niche differentiation of these species. Data such as light amount and proximity to water of the patch sites were gathered to provide information about territorial preferences of these two species. No significant relationships between patch fidelity and patch characteristics were found. A significant difference was seen between the patch fidelity of the two species, implicating territory as a possible niche differentiating mechanism. Possible explanations for the variation in patch fidelity behavior between the species include: genetic differences between the two species, differences in learning abilities in relation to life span, and differing impacts of population dynamics on H. cruentata and A. extranea.
Fidelidad a pequeños parches entre dos especies de libélulas de la familia Odonata, Hetaerina cruentata y Argia extranea, fue investigado para determinar si hay una diferencia en la conducta territorial de las especies.
