Materials and Methods

Specimen data were obtained for the University of Guelph Insect Collection (DEBU), the Royal Ontario Museum (ROM) and the Canadian National Collection of Insects, Arachnids and Nematodes (CNC).

Terminology used in the key follows the Manual of Nearctic Diptera (McAlpine et al., 1981) and is depicted in Figures 1–5. The use of the word “tergite” refers to abdominal tergites. Diagnoses for species are based on specimens from the University of Guelph Insect Collection where possible, but in some cases photos of type specimens were used instead. When only one specimen of a species was available, photos from BugGuide ( 15740) were used to indicate variation within species. Diagnoses were checked against the original descriptions, Bullington (1986), and Baker and Fischer (1975). Body length data were supplemented from the literature. Flight ranges were determined using label data from DEBU and CNC. Distribution maps were created using the online software SimpleMappr (Shorthouse 2010). Locations were obtained from specimen data labels and were converted to GPS coordinates using Google Maps GPS Coordinates ( Non-Ontario distributions were mapped using whole provinces, territories or states to indicate the presence of Laphria within these jurisdictions. Specimen photographs were taken using a Canon DSLR mounted on a Stackshot rail, and then stacked using Helicon Focus. All photographs of living flies were taken by the second author unless otherwise indicated.
