The upright male position during oviposition as an anti-predator response in Coenagrion puella (L.) (Zygoptera: Coenagrionidae)
Odonatologica , Volume 20 - Issue 1 p. 69- 74
In i C. puella tandem pairs oviposit with the male positioned rigidly upright on the prothorax of the female. At the oviposition site during windy weather males may spontaneously settle in a horizontal position in front of the female. In this situation predation risk from approaching predators (green frogs) was greatly increased. Disturbance experiments with groups of pairs with both types of male positions show that tandems with male upright make a speedier escape than pairs with males horizontal. In pairs of the latter kind males have to take up an inclined or upright position before take off, so that the pair remains longer within range of an approaching predator.
