Coexistence of three Sympetrum species at Den Diel, Mol, Belgium (Anisoptera: Libellulidae)
Odonatologica , Volume 16 - Issue 4 p. 347- 360
In an Odonata community of the NE of Belgium 7 Sympetrum spp. coexist. Resource partitioning between 3 of them, S. depressiusculum, S. danae and S. pedemontanum, was studied. Habitat separation was found between pedentontanum versus depressiusculum and danae and separation in adult diurnal activity-pattern between depressiusculum versus danae and pedemontanum. Although the interactions between depressiusculum and danae are reduced by differences in diurnal activity and to some extent by seasonal separation, they interact frequently and aggressively. The pioneer characteristics of S pedemontanum are discussed.
