One species is the brilliant-colored rainbow jetdarters, which can flash through foliage in small, scavenging schools. Another species is the cobalt jetdarter, which makes polyhedral hives in plaque-bark trees (sometimes in trees that grow on the backs of keeled grove-backs). In attendance to a large predator chasing down a smaller-sized prey animal, a school of jetdarters will follow, the small flyers opportunistically sensing an imminent kill. It, itself, is the main prey of the finned snapper.
