On some aspects of reproductive behaviour in Chloroneura quadrimaculata (Rambur) (Zygoptera: Protoneuridae)

The observations were carried out at a hill stream, Sagar District, Madhya Pradesh, India. Territoriality was strongly demonstrated by males which also exhibited precopulatory courtship by "wing display” before assuming the tandem position. Intra-male sperm transfer occurred after the seizure of the female and lasted for 18.8 sec. The copulatory wheel was formed in the perched condition and was maintained for 4.1 min, during which insemination took place. After disruption of the wheel position, the tandem pair performed postcopulatory exploratory flights which lasted for 20.8 min. The sensory styles of the ovipositor valvulae helped in the exploration of suitable sites and materials. Oviposition occurred in tandem and lasted for 20.3 min. The eggs were laid irregularly and exophytically among the algal mass and were covered by a gelatinous investment.
