Where do Giant Water Bugs typically lurk during the day to ambush prey?

Beneath submerged debris or among aquatic vegetation

Giant Water Bugs are highly efficient ambush predators, and their daytime behavior reflects this necessity for cover. They avoid swimming openly in the water during daylight hours. Instead, they position themselves strategically under materials that provide camouflage and concealment, such as submerged debris piles or dense masses of aquatic plants like cattails or lily pads. This allows them to remain undetected while patiently waiting for smaller aquatic life, such as tadpoles or small fish, to venture close enough to attack.
