Scientific Name: Macropis patellata Patton, 1880
Common Name: Macropis patellata Patton
Macropis patellata Patton, 1880: 33 [â™‚,â™€]
Syntypes â™‚,â™€. USA, Connecticut, Plymouth, 1 August [no year provided], by H.F. Bassett, on Cicuta or Rhus; Connecticut, Waterbury, 9 July [no year provided], by W.H. Patton, on Lysimachia ciliata 
Though no specific localities are provided, Snelling and Stage (1995) indicated that this species occurred in [eastern] Canada, based on discussion of type localities of material described by Provancher, though this is not indicated in the range listed later in that work. However, its known proximity to eastern Canada (southern Ontario and Quebec) indicates that it likely does occur in Canada.
The DNA Barcode Index Number (BIN) for this species has not been assigned.
This species, like all bees of the genus Macropis, is a oligolege on oil producing flowers of the genus Lysimachia (Popov 1958; Cane et al. 1983; Michez and Patiny 2005; Dötterl and Schäffler 2006). This species is likely a host for the cleptoparasitic bee, Epeoloides pilosulus in North America (Sheffield et al. 2004; Sheffield and Heron 2018).
