What structural residue is sometimes left behind near submerged vegetation indicating a giant water bug has successfully hunted?
Answer
The empty, often translucent husks of their prey.
Observing the aftermath of a giant water bug's hunt can sometimes reveal signs of their meal, even if the bug itself is not visible. Unlike terrestrial insects that might leave behind chewed casings, the GWB's method involves extracting all the internal fluids. Consequently, the only material left is the external structure of the prey item. This residue typically manifests as empty, often translucent husks of whatever was consumed—whether it be the shell of a snail or the outer casing of a small water beetle—after the nutritious internal contents have been fully ingested.
