| From time to time the backswimmer will surface to empty and refill these chambers with a fresh supply of air. |
|
| Holding its pale back away from the sunlight makes the backswimmer harder for predators to spot. |
|
| 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. |
|
| Because the backswimmer is lighter than water, it rises to the surface after releasing its hold on the bottom vegetation. |
|
| So here, we have a backswimmer, an unusual insect because it swims backwards. |
|
| The backswimmer is often seen floating on the water surface with its legs extended, ready to dart away if disturbed. |
|
| When the arriving female mosquitoes detect a chemical emitted by the backswimmer, they are less likely to lay eggs in that pool. |
