First recorded in North America on Long Island in 1981. "Our limited observations suggest that P. variabilis is a univoltine, early season mirid associated mainly with staminate inflorescences of oaks. Based on the European literature and our collections, adults on Long Island probably appear by mid-May and are present only until mid- to late June...Psallus variabilis appears well established on Long Island, and the large numbers found on native scrub oak suggest that it has been present for several years, if not longer." (Wheeler, 1982). Found on S wall midday. Larger image.
