Very little information is available on the biology of the bladetail (8). However, reproduction in dragonflies generally involves very little courtship behaviour, and begins with the male grasping the female by the back of the head with the anal claspers. Mating then takes place in the air, on the ground or among vegetation, with the length of the process varying greatly between species (10).
Like other dragonfly species, the bladetail is thought to have a complex life cycle which includes a fully aquatic nymphal stage (10). As a nymph, the dragonfly is an effective sit-and-wait predator with the unusual feature of being able to fire out the lower portion of its mouth in order to grasp passing prey (10) (11).
As well as being able to walk, dragonfly nymphs are able to move through the water by jet propulsion, expelling water from a specialised rectal chamber in order to propel themselves along (11). The total length of time spent in the nymphal stage varies between dragonfly species, with some species spending a few months and others several years as a nymph (10).
Adult dragonflies are skilled aerial predators, usually catching various small insects on the wing (10).
The adult bladetail has been reported to roam over relatively large distances, and as a result it is thought that this species is able to recolonise old sites or settle in new bodies of water. This ability to colonise unstable, arid environments is a result of a combination of factors, including the migratory ability of the adults, their preference for breeding in stagnant water, and the fact that the nymphs are able to tolerate salinity (8).
