Species Notes

The cleptoparasite of this species was assessed as Endangered in Canada by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) (COSEWIC 2011).

The DNA Barcode Index Number (BIN) for this species is BOLD:AAD9500.

 

Biology

Patton (1879) was among the first to recognize and detail the relationship of Macropis bees to Lysimachia. Rozen and Jacobson (1980) and Cane et al. (1983) studied the nesting and mating behaviours in detail, the former describing the immature stages. 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), but visits a number of other genera for nectar. This species is likely the main host for the cleptoparasitic bee, Epeoloides pilosulus in Canada (Sheffield et al. 2004; Sheffield and Heron 2018).
