Colletes aestivalis Patton, 1879
Properties
Scientific Name: Colletes aestivalis Patton, 1879
Common Name: Colletes aestivalis
Taxonomy
Colletes aestivalis Patton, 1879: 142 [♀].
Neotype ♀, designated by Stephen (1954: 283). USA, Maryland, Cabin John, 1 June 1918, by R.M. Fouts [USNM no. 534546].
Colletes heucherae Robertson, 1891: 61 [♀, ♂]. Synonymy by Robertson (1895: 116).
Lectotype ♀, designated by Stephen (1954: 283)]. USA, Illinois, Carlinville, by C. Robertson [INHS no. 3996].
Taxonomic notes: Records of this species from Manitoba likely represent C. andrewsi Cockerell, 1906 (see Stephen 1954: 283), as was the case for material identified as C. aestivalis Patton, 1879 by Graenicher (1935: 302) (see Stephen 1954: 281).
DNA Barcode Index Number (BIN): N/A
Biology: Colletes aestivalis is an oligolege of Heuchera (Fogel et al. 2023).
Distribution in Canada: Criddle et al. 1924 [MB]; Michener 1951 [MB]; Romankova 2003 [ON].
Stephen (1954: 283) indicated that this species likely did not range further west than southern Illinois, and though he did not record it from eastern Canada, the records of Romankova (2003: 99) are plausable. As discussed above, records of this species from Manitoba likely represent C. andrewsi, so are not included.
Body length: ♀ 12 mm ♂ 12 mm
Forewing length: ♀ 7.5 mm ♂ 7.5 mm
