Bagworms Eat (Almost) Everything

Abstract

Larvae of the evergreen bagworm continue to feed after they are transferred from one host plant species to another. Periods as long as three generations on a single host plant apparently do not bring about any significant dependence on that host. Trees of host species that are uninfested or lightly infested in areas of high insect depredation may be marginally resistant to the local insect population, but are probably not genetically resistant to the insect species as a whole.
