Distribution. USA: CA, *MA, *ME; Canada: AB, MB, NB, NS, ON, QC.
Comments. The type series was reared from larvae collected in Alberta and Manitoba on June 16, June 29, and July 15. Our rearing records indicate this species is at least bivoltine in New England, with larvae occurring in June and early August. A larva collected in early July proved to be another species (Liriomyza sp. 1, below). The only Liriomyza mines we have found on Maianthemum racemosum were already empty at the end of May.
