Lipara Meigen

Two species of Lipara, each represented by a single female specimen, were collected at the Terra Cotta site in 2011. Lipara rufitarsis is widespread and abundant in the northeastern United States (Tewksbury et al. 2002) so its eventual establishment in adjacent regions of Canada was predictable. The Quebec specimen (CANADA: Quebec: Pointe-Claire, Terra Cotta Natural Park, 45.4516° -73.8103°, 15–21.vi.2011, C. Barrie, yellow pan trap, old field, 1 ♀, LEM) represents the first published Canadian record of the species and the genus.

Although Lipara lucens was the first species of Lipara collected in North America, in 1931 (Sabrosky 1958), it does not seem to have been recorded here since that first collection and Tewksbury et al. (2002) did not consider it established in North America. The single specimen of L. lucens collected in this study (CANADA: Quebec: Pointe-Claire, Terra Cotta Natural Park, 45.4516°, -73.8103°, 02–07.vi.2011, C. Barrie, yellow pan, old field, 1 ♀, LEM) provides evidence that L. lucens may have been introduced on multiple occasions and may be established in Canada.
