Who can eat fern caterpiller snailwhale or moth?

Fern caterpillars can be consumed by various predators, including birds and some insects. Snails typically feed on plant material, not caterpillars or moths. Moths can also be preyed upon by birds and other insectivores, but they primarily feed on nectar and do not eat caterpillars. In summary, birds are the primary consumers of both fern caterpillars and moths.
