Pond walkers: their unique role in wetland environments

Pondlings, also known as water runners, are intriguing insects that live on the surface of still waters such as ponds and lakes.

What makes pond runners unique?

Pondlings belong to the order of semi-wings and are known for their ability to walk "over" water. This is possible thanks to the special structure of their legs, which are covered with fine, water-repellent hairs. These hairs prevent the legs from sinking through the surface of the water, making the insect dance on the water, so to speak.

How do pond runners move about?

Their mode of locomotion on the water surface is both agile and fast. This enables pondrunners to easily catch prey and evade predators. They use the surface tension of the water to propel themselves, a fascinating feat of physical adaptation.

Nutrition and hunting strategy

Pondlings feed on small insects and other small animals that live on the water surface or fall into it. Their hunting strategy is unique: they detect vibrations on the water surface caused by potential prey. Once they detect prey, they move quickly to catch it with their front legs.

Reproduction and growth

The reproduction of pondlings begins with the laying of eggs, often on plants near the surface of the water. The larvae that hatch from these eggs already closely resemble adult pondlings. They go through several molt stages before becoming adults, a process that is fascinating to observe.

Life span and living conditions

Pondrunners prefer still or slow-flowing waters. Their lifespan varies, but many species live only one season. Their survival is highly dependent on water quality and food availability.
These insects play an essential role in their habitat. They help regulate the population of smaller aquatic animals and contribute to the decomposition of organic matter. Their presence is often a good indicator of water health.

Conclusion

Pond walkers are remarkable insects that excel in their ability to "walk" on water. Their adapted hunting techniques and life cycle make them fascinating inhabitants of our wetland environments. By understanding their behavior and way of life, we appreciate the complexity and beauty of life on the surface of water.
