Target species affects the duration of competitive interactions in the Neotropical dragonfly, Micrathyria atra (Odonata: Libellulidae)

摘要

Dragonflies often engage in aggressive interactions over access to mates, food, or other resources. We should expect species to have behavioral adaptations for minimizing such interactions with other species because they are not competing with them for mates and often require different resources. We conducted observational trials in natural water pools that provide new evidence for one such adaptation in the Neotropical dragonfly, Micrathyria atra: males in this species have shorter interactions with individuals of other species than with conspecifics.
