Andrena accepta Viereck, 1916


Scientific Name: Andrena accepta Viereck, 1916

Common Name: Two-spotted Miner Bee


Andrena pulchella Robertson, 1891: 57 [♀]. Preoccupied, not Andrena pulchella Jurine, 1807.

     Lectotype ♀, designated by LaBerge (1967: 66). USA, Illinois, Carlinville, 30 August to 20 September [no year provided], by C. Robertson, on Helianthus grosse-serratus and H. rigidusi [INHS no. 8637].

Andrena accepta Viereck, 1916: 127. New name for A. pulchella Robertson, 1891.


Taxonomic notes: The ♂ was recognized by Robertson (1895: 119).

The syntype series of A. puchella consisted of 7♀s. Thus, the lectoallotype designated by LaBerge (1967: 66) is not valid, in addition to being based on material collected by Robertson in 1893, two years after this species was described.

DNA Barcode Index Number (BIN): BOLD:AAJ2047

Biology: Rozen (1973) described the nest and mature larval stage, and indicated that this solitary bee can nest communally. This species is broadly oligolectic on Asteraceae, but seems to prefer the pollen of Helianthus. This species is widespread in the United States, though has been recorded from Canada only once (LaBerge 1967).

Distribution in Canada: Criddle et al. 1924 [AB]; LaBerge 1967 [AB]; Sheffield et al. 2014 [AB].
