Abstract: 4 tables. [Feeding habits of the slug were investigated in Shenanoah National Park. "Slugs apparently do not feed on those lichen species most frequently encountered in the community. Rather, they appear to make food choices that are based at least in part on lichen chemistry. Stictic acid and protocetraric acid appear to function as anti-herbivore compounds in observed lichen-slug interactions."]
