Generally, water striders will try to disperse in such a way to lower the density of gerrids in one area or pool of water. Not us humans but small insects such as the water strider can walk on water because their weight is not enough to penetrate the surface. Water spiders look grayish brown when they aren't in the water, but in the water they have a shimmery silvery look.

Water spiders live in Europe and northern and central Asia. The legs of a water strider are long and slender, allowing the weight of the water strider body to be distributed over a large surface area. Antennal segments are numbered from closest to the head to farthest. Did you know that there is a spider that lives most of its life underwater?

Instead of competing to reproduce, water striders can work together to obtain nutrition and shelter outside of the mating season. These spiders usually live for about two years. Since internal genitalia require specific training and tools to identify, it is almost impossible to tell a member of the Gerridae apart from a member of the Veliidae by external visual cues. I am able to slide along I’ve written about how mosquitoes may be annoying, but they do serve as a source of food for other animals, including water striders. 1 Relative lengths of the antennae segments can help identify unique species within the family Gerridae, but in general, segment I is longer and stockier than the remaining three. display: none !important; True bugs are one of the orders within the broad grouping of insects (the Class).
