Larval behaviour of a giant damselfly: territoriality or size-dependent dominance?
Article Abstract:
The behavior and territoriality instincts of the larvae of the giant damselfly Megaloprepus coerulatus in Panama were studied. Larvae used agonistic behavior to displace others from a habitat. Possession of cover seems to be important to the M. coerulatus for the avoidance of predation by conspecific and heterospecific odonates. There is a lack of territoriality in M. coerelatus. Habitat displacement of smaller larvae by larger ones seems to be size-dependent in nature.

Components of lifetime mating success and body size in males of a scrambling damselfly
Article Abstract:
The hypothesis that sexual selection favours small body size in males of scrambling species was tested in the scrambling emerald damselfly, Lestes sponsa. The critical factor explaining variation in male lifetime mating success (LMS) was mating efficiency. A small quality factor was found to positively affect mating efficiency and life span.

Copulation duration and fertilization success in a damselfly: an example of cryptic female choice?
Article Abstract:
Research is presented describing the testing of 4 adaptive hypotheses of cryptic female choice,time constraints, sperm displacement, in-copula mate guarding, to explain the variation (0.5 - 3 h) of copulation duration in the damselfly, Ceriagrion tenellum (Coenagrionidae).
