As anyone who visits the FWG knows, the dog-strangling vine (DSV) (pale swallowwort) is an abundant and aggressive invasive species. Biologists are looking for bio-control agents as a method of helping control this plant. While not much feeds on the DSV, we have always noticed signs of some herbivory. This particular leaf caught my eye as the leaves were chewed much more so than one usually sees in this plant.
