Not sure which species this one is, but Languria bicolor is famous for chewing lots of little holes (at night, thus mysteriously to most people) in the leaves of Arnoglossum spp. (Asteraceae: tribe Senecioneae). Several interesting species of this genus inhabit better quality natural community remnants in eastern US.
