Little information is available on the biology of Ischnura abyssinica, but there is currently an ongoing study to identify and record more information on this and many other species of African invertebrates (4).
Like most damselflies, Ischnura abyssinica is likely to have a fluttering weak flight pattern and be found at freshwater sites, sometimes massing in numbers exceeding hundreds of individuals. The male damselfly will typically remain close to the water source and is often stationary amongst the vegetation at the water edge. The female may be found in remote areas such as meadows, away from water sources (2).
In most damselfly species, the adult male will patrol a territory along the water edge, and will secure a mating with many different females. The male will often guard the female from competing males while the eggs are being laid. The female lays eggs inside vegetation underneath the water. Once hatched, the larvae feed on a variety of food types, from small organic matter to larger invertebrates. In most damselfly species, the development of the larvae is completed within one to two years (2). The larvae development can be very rapid, as they develop in stagnant water (2) (3).
Adult damselflies are ferocious aerial predators, usually feeding on mosquitoes and midges (2).
