frequently asked Questions

Can hawkmoth caterpillars cause itching or allergies?

Although the caterpillars of the hawk moths look impressive with the stinger on their abdomen, they are harmless to humans. In contrast to them, caterpillars of the oak processionary moth (Thaumetopoea processionea) can cause severe itching and skin irritation.

How do you protect garden plants from damage caused by caterpillars?

Without caterpillars there are no butterflies and no moths! Most caterpillars do not cause much damage. Provide good nesting opportunities for songbirds. Protect endangered plants by collecting them regularly and using glue rings.

What natural enemies do butterfly caterpillars have?

Important enemies of the caterpillars are parasitic wasps and sand wasps. Ichneumon wasps lay their eggs in the bodies of the caterpillars, which then die off. Sand wasps paralyze butterfly caterpillars with a poison and gradually eat them up.
