Dragonfly death by entanglement on hooked and barbed plant surfaces (Anisoptera: Libellulidae)
Odonatologica , Volume 20 - Issue 1 p. 79- 83
Entanglement and death of young and old male Trithemis arteriosa and T. dorsalis on the hooked trichomes on the seed pods of the indigenous plant Desmodium repandum and on the barbed points on the seed heads of the exotic Bidens pilosa are illustrated and described from South Africa. These hooks and barbs, although probably having evolved for epichory (= epizoochory) in fur and feathers, are lethal traps for these dragonflies.
