Ophiomyia kwansonis Sasakawa, the daylily leafminer (DLM), previously known only from Japan and Taiwan, and present but unidentified in the continental United States since at least 2008, is here documented from detections made in 2011. Known distribution, including U.S. and European records, is given, with a number of new state records documented by photographic images of the characteristic, unique larval feeding damage found in Hemerocallis spp. Some biological observations are also included.
