Ecology: Instream habitat: Commonly known as ‘giant water bugs’, Belostomatidae species live in wetlands, ponds and lakes that have plenty of aquatic vegetation in the littoral zone. Feeding ecology:Belostomatid bugs are good swimmers, able to chase after their prey over a short distance, although they spend most of their time hanging in the water column waiting for an opportunity to catch prey. They are voracious predators, becoming a nuisance in fish farms and can inflict a painful bite upon humans. Their large size means belostomatid bugs are often at the top of the food chain and are one of the few invertebrates that can readily feed on small fish as well as other invertebrates, including their own species. Habit: Life history: The female Diplonychus lays her eggs on the back of the male. In this position they are safe from the male and other predators. The male strokes the eggs with his hind legs to maintain a fresh flow of water, but if an egg gets dislodged he readily eats it. Belostomatid nymphs stay away from adults to avoid being eaten. Males have been reported to make stridulatory sounds to attract females. They initiate mating by "display pumping" or rhythmical push-up-like body movements near the surface of the water. |
