What specific risk is posed by offering a dish of water to the fuzzy caterpillar body?

Answer

Drowning risk due to the fuzzy body getting trapped

While caterpillars derive sufficient moisture directly from the leaves they consume, if an observer chooses to offer water, caution is paramount. Although a shallow cap can work safely, providing a dish of water poses a significant threat. Because of their fuzzy bodies, the caterpillars can easily become trapped in standing water, leading directly to a drowning risk. This danger overrides concerns about dehydration, which is generally managed through their leafy diet. While excessive moisture in the substrate can cause other problems, a dish of standing water presents an immediate physical hazard to the larva itself.
