Certain caterpillars eat plants that are toxic to both themselves and the parasite to cure themselves. [24] Drosophila melanogaster larvae also self-medicate with ethanol to treat parasitism. [25] D. melanogaster females lay their eggs in food containing toxic amounts of alcohol if they detect parasitoid wasps nearby. The alcohol protects them ...

Even in the case of defoliation, the species does not generally kill plants. The caterpillars are large and conspicuous and can be controlled by plucking them from the tree. [2]
