How Do Water Striders Walk on Water


The water strider is a fascinating creature. It’s able to walk on water due to a combination of factors, including its hydrophobic legs and its weight distribution. Its legs are covered in tiny hairs that repel water, and when combined with its light weight, this allows it to float on the surface of the water.

The water strider also has a long body that helps it keep its balance, and its feet are specially adapted for walking on water. All of these factors come together to allow the water strider to perform one of nature’s most impressive feats.

Have you ever seen a water strider walking on top of water? It’s a pretty amazing feat, but have you ever wondered how they do it? Water striders are able to walk on water because of their hydrophobic legs.

Hydrophobic means “afraid of water”, and in this case, it means that the legs repel water. This allows the water strider to create a surface tension on top of the water that they can then walk on. Interestingly, not all insects are able to do this.

In fact, most insects will sink if they try to walk on water. So, if you see an insect walking on top of a pond or lake, chances are good that it’s a water strider!

Why Do Water Striders Need to Walk on Water

Water striders are a type of insect that can walk on water. They have special adaptations that allow them to do this, including long legs and a small body. Water striders use their legs to create a surface tension on the water, which they can then walk on.

This is similar to how we can walk on the moon because of the low gravity. Water striders are found all over the world and in many different habitats, from ponds to lakes and even rivers. They are predators and eat other insects that fall into the water.

Water striders are an important part of the ecosystem and help to keep populations of other insects in check. So why do water striders need to walk on water? It’s an adaptation that helps them survive in their environment.

By being able to walk on water, they can access areas where other insects cannot go. This gives them a competitive advantage when it comes to finding food. Additionally, walking on water helps them avoid predators, as many animals cannot reach them when they are standing on the surface of the water.

How Do Water Striders Move on Land?

Water striders are small, dark-colored insects that can be found near the water’s surface. They have long legs and a slim body that helps them move quickly across the water. But how do they move on land?

Water striders use a special technique to walk on land. Their legs are specially adapted to grip the ground, allowing them to walk without slipping. They also have a pair of claws at the end of their legs that help them grip the ground and keep their balance.

When walking on land, water striders keep their abdomens close to the ground. This helps them keep their balance and prevents them from tipping over. If you watch a water strider carefully, you’ll notice that it often waves its front legs back and forth as it walks.

This helps it maintain its balance and keeps it moving forward in a straight line. So next time you see a water strider, take a closer look and marvel at this insect’s amazing ability to move on both land and water!

Can Water Striders Walk on Land?

While water striders are most commonly found near or on the surface of freshwater lakes and ponds, they are also known to venture onto land in search of prey. When doing so, water striders are able to walk across the ground using their long legs and sharp claws. Although they are not speedy runners, water striders can cover a fair distance on land before needing to return to their aquatic habitat.

Can a Water Strider Sink?

Yes, a water strider can sink if it is not touching the surface of the water. The water strider has hydrofuge hairs on its legs that allow it to walk on the surface of the water. These same hairs also help repel water, so if the water strider is not touching the surface of the water, it will eventually sink.

How Do Water Striders Propel Themselves?

Water striders propel themselves using surface tension. Surface tension is the force that makes water bead up into drops. It’s caused by the attraction between water molecules.

Water striders take advantage of this property to walk on water. They do this by first hairy legs which increases the surface area that is in contact with the water molecules, and secondly, by having an oily layer on their legs which further reduces the amount of friction between their legs and the water’s surface. This allows them to “skate” across the top of ponds and lakes with ease!


Water striders are able to walk on water due to the hydrophobic nature of their legs. The water strider’s legs are covered in tiny hairs that repel water, allowing the insect to stand on top of the surface tension. This ability allows water striders to prey on other insects that become trapped on the water’s surface.
