About Bradinopyga geminata (Rambur, 1842)
Bradinopyga geminata is a medium-sized dragonfly. It has brown-capped grey eyes, a cinereous thorax irregularly marbled and speckled with black, and transparent wings with dual-colored pterostigmata: black in the center, and pure white at the distal and proximal ends. Its abdomen shares a similar color scheme to the thorax, with black marbled with yellow following a more defined pattern. Segments 3 through 8 have pale basal rings interrupted on the dorsum, formed by two elongated parallel spots. Each of these segments also has a triangular apical sub-dorsal spot and a pale mid-dorsal spot. Its anal appendages are creamy-white, and females are similar in appearance to males. Thanks to its cryptic coloration, the species always rests flat on slab rock or cement-plastered walls, where it is almost invisible. Adult dragonflies live in habitats near water bodies, including pools, irrigation channels, wells, and containers holding standing water. This species breeds in rain-filled hollows in rocks, wells, and small cemented tanks. Bradinopyga geminata has been studied as a predator of the disease-carrying yellow fever mosquito, Aedes aegypti. Dragonfly larvae consume Aedes aegypti larvae in the shared standing-water habitats both species occupy.
