What bugs eat petunias?

Aphids, budworms, cutworms, earwigs, flea beetles, hornworms, leafminers, mites, spider mites, and thrips are bugs that eat petunias. The Word bug either loosely designates certain arthropods (arachnids, insects, myriapods, terrestrial crabs, woodlice) or strictly references insect members of the Coleoptera order. The above-mentioned examples fit into the more liberal meaning since many animals -- including deer, rabbits, and slugs -- and pathogens -- blights, rots, viruses, and wilts -- enjoy ravaging external and internal petunia plant parts.
