Sitochroa palealis (Denis and Schiffermüller) is recorded from North America for the first time. Adults were collected in Illinois, Indiana, Michigan and Wisconsin. The capture of larvae and adults in four states over a six-year period is strong evidence that S. palealis is established in North America. Characters separating S. palealis from other Sitochroa in North America are given. The potential impact of S. palealis to prairies, agriculture, and biocontrol of noxious weeds is discussed.
