NATURE

        Have you ever watched the tiny
        flying insects hovering over a

        still body of water such as a
        dam, a pond or even a puddle?
        In this miniature world there
        is a whole microcosm of life
        that struggles to survive whilst

        preying on anything smaller
        than themselves and trying
        to reproduce as quickly as

        possible in their short lifespan.
        Dragonflies and damselflies live
        in this precarious environment
        and can often be seen darting
        around the periphery of ponds,

        dams and lakes.

        their well-developed mouth parts.

        Adult dragonflies and damselflies often
        fall victim to birds such as rollers and
        bee-eaters and other unfortunates fly into
        spiders’ webs with fatal consequences.

        Both species lay their eggs in water, the
        quantity of eggs varying from dozens to
        hundreds depending on the species. Water   Red Veined Dropwing
        temperature often affects hatching and
        some eggs laid late in the summer season
        may only hatch into nymphs during the next
        season. The nymphs then enter the larval
        stage and remain in the water for some two
        months in the case of small damselflies
        and up to a year for the larger species. The
        nymph sheds successive skins as it grows
        until finally it emerges from the water where
        it metamorphoses into an adult, leaving
        behind the cast-off larval shell.

        Life expectancy for an adult damselfly may
        be only a month while adult dragonflies
        may expect to live for around two months   Violet Dropwing male             Mating Maisai Sprites
        although the larger dragonfly species may
        survive for a whole summer.

        In South Africa, dragonflies and damselflies
        are seldom seen during the colder winter
        months but during the warmer spring and
        summer months they can be seen regularly
        over ponds and lakes.

        Some of the dragonfly species that we've
        seen recently are Red-veined dropwing,
        Violet dropwing, Highland dropwing and
        Broad Scarlet. Damselfly species include
        the Masai sprite, Slate sprite and Tropical
        bluetail.                                 Tropical Bluetail                 Anthony taking photos at a dam
