Stephanitis blatchleyi, described in 1925, is a rarely collected lace bug known only from a few localities in peninsular Florida; its host plants previously were unknown. We observed adults, nymphs, exuviae, and foliar chlorosis on the ericaceous shrub rusty lyonia (Lyonia ferruginea) at a site in Clay County, Florida, from December 2007 to October 2012. Feeding symptoms wereconfined to leaves of lower branches. Although the tingid was not found elsewhere in Florida on L. ferruginea (or on L. fruticosa), additional fieldwork probably will show that S. blatchleyi is more widespread than suggested by our sampling.
