Virtually nothing is known about the biology of the Hajar Wadi damsel. However, its lifestyle is likely to be similar to that of other damselfly and dragonfly species. A damselfly begins life as an aquatic larva, known as a nymph, which passes through a number of developmental stages, or ‘stadia’, and undergoes several moults as it grows. Shortly before the final moult (emergence), the nymph ceases to feed, and moves close to a site where it can emerge, such as a water plant, rock, or the shore. It then undergoes metamorphosis, changing into the adult form (5).
The newly emerged adult will spend a few days to several weeks feeding and maturing, usually in a protected, prey-rich site. During this pre-reproductive phase, the damselfly can be identified by a glassy sheen to the wings, and it is usually during this time that the full adult colour develops. Mature males may defend a territory against rival males, and competition for females can be fierce. The male will guard the female while the eggs are laid, to prevent other males mating with her. Both adults and nymphs are impressive and opportunistic predators, feeding on a variety of prey (5).
