| The grousewinged backswimmer, N. undulata, found in North America, can often be seen swimming under the ice during the winter. |
| So, the backswimmer swims backwards, and it is also a predator that has developed quite a strategy for breathing in the water. |
| The backswimmer is often seen floating on the water surface with its legs extended, ready to dart away if disturbed. |
| Because the backswimmer is lighter than water, it rises to the surface after releasing its hold on the bottom vegetation. |
| When the arriving female mosquitoes detect a chemical emitted by the backswimmer, they are less likely to lay eggs in that pool. |
| Influence of the predatory backswimmer Notonecta maculata, on invertebrate community structure. |
