Is it ok to hold a caterpillar or will it affect their lives?

Holding a caterpillar is generally safe, but it's important to do so gently and briefly to avoid stressing the insect. Caterpillars have sensitive skin and may absorb oils or chemicals from human hands, which can harm them. Additionally, frequent handling can disrupt their natural behaviors and development. If you must hold one, ensure your hands are clean and dry, and return it to its environment as soon as possible.
