Instead of flying, water skimmers rely on their speed, agility, and powerful legs to navigate their world on water.
How do water skimmers reproduce?
Water skimmers, also known as family Hydrophilidae, are aquatic insects that can be found in ponds, lakes, and slow-moving streams. These fascinating creatures reproduce through a process called ovipositing, where the female water skimmer lays her eggs in the water’s surface. The female typically selects a suitable location, such as a submerged twig or a floating plant, to deposit her eggs, which are usually yellow or cream-colored. The eggs hatch into water skimmer larvae, which feed on small aquatic animals, algae, and other organic matter. During the larval stage, the young water skimmers undergo a series of molts, growing and developing until they reach the pupal stage. The pupal stage marks the final transformation, and adult water skimmers emerge, ready to start the reproductive cycle anew. With proper habitat and food conditions, water skimmers can complete multiple generations in a single year, making them an important part of aquatic ecosystems.
What are water skimmers’ predators?
Though they might seem quite hardy with their large appetites, water skimmers are not without their enemies. Large fish, like bass and catfish, are known to prey on water skimmers, while birds such as great blue herons and kingfishers also pose a threat. These aerial predators use their keen eyesight to spot the busy skimmers hovering near the water’s surface, swooping down to snag them with lightning reflexes. Even snakes and some larger aquatic turtles will occasionally make a water skimmer one of their meals.
Can water skimmers live in polluted water?
