The water strider can walk on water without sinking into it. As this water creature has three pairs of legs, it uses its middle pair to float on the water surface. This pair of legs is also used as oars to row a boat, and the rear pair of legs is used for steering purposes. Its weight also helps him to float off the surface evenly.

7. Social Behavior of Water Striders

Research has shown that water striders are the most enjoyable water creatures to be observed. They are mostly found in the lakes and ponds of Northern Hemisphere. Up till now, there are 1700 species of water striders observed. They usually avoid getting captured by predators. Many types of research are done to them because of their ability to walk on the surfaces of water. Sometimes these aquatic creatures are confused with other aquatic insects such as Velarde. The territories are different for both ma eater striders and the female water striders. It is observed that the male territory is slightly larger than the female ones. When the mating seasons comes, these territories also emit vibrations to defend themselves. As there is no need to compete in routine, so they make large groups and roam around during none mating season. They also sometimes work together in groups to look for food and shelter. The groups formed by them become denser and they tend to disperse. They have no familial tendencies; they tend to leave the newly hatched offspring to avoid any cannibalism.

8. Mating Behavior of Water Striders

The mating process between the water striders starts unceremoniously. The male water strider simply mounts on the female without any foreplay. The chances are that she may try to resist, but even she does the male water strider will actively start to strum the water. The vibrations can attract the predators such as fish or birds. As the female is under the male, she will readily accept any assault. The male member has no concern with the pregnancy process; he does not have to look after the next generation. As he has plenty of sperm, he can mate as many females as he can. As compared to male water strider female has limited opportunities to lay eggs. The female water strider usually lowers her abdomen to allow the male mount on her easily. The female who does not want to allow the male to mate will raise her abdomen. It is also said that males that have access to mate the female remain with the same throughout the mating season. This makes sure that the young ones produced by the females are belonging to the mounting male sand in this ay it can spread its sperms. Some female prefers laying eggs at water edge where the water is calm and peaceful. The number of eggs laid by the female depends on the amount of food that is available to the female throughout the season. The duration of hibernation depends on the warmth of environment.
