Epeolus ainsliei Crawford, 1932


Scientific Name: Epeolus ainsliei Crawford, 1932

Common Name: Ainslie s Cellophane Cuckoo Bee


Epeolus ainsliei Crawford, 1932: 74 [♀].

     Holotype ♀. USA, Iowa, Sioux City, 15 July 1922, by C.N. Anislie [USNM no. 534035].


Taxonomic notes: The ♂ was first described by Brumley (1965: 27), and more recently treated by Onuferko (2017: 21).

Onuferko (2021) described a form of this species in which the pubescence of the terga was extensively pale, and indicated that it is quite variable.

DNA Barcode Index Number (BIN): BOLD:ACZ1957.

Biology: Onuferko (2018) suggested that Colletes susannae Swenk, 1925 could be the likely host of this species as the two have been collected together in Manitoba in Canada, and in Wisconsin, USA (Wolf and Ascher 2009). However, other species of Colletes were also observed at these localities.

Distribution in Canada: Brumley 1965 [AB, MB]; Sheffield et al. 2014 [AB, MB]; Onuferko 2017 [AB, MB], 2018 [AB, MB, ON], 2021 [MB]; Gibbs et al. 2023 [MB].
