Andrena (Trachandrena) heraclei Robertson 1897

County records: Allegan.

Notes. Andrena heraclei , originally described from Carlinville, Illinois, has been recorded previously from southern New England and New York, where it is rarely collected (JSA, unpublished), to Kansas ( LaBerge 1973). These new records extend the northern range of the species in the Midwest. A male of A. heraclei was collected in a blueberry field, but misidentified as the similar species A. spiraeana Robertson ( Tuell et al. 2009) . Females of A. heraclei were collected at the same site nine years later ( Gibbs et al. 2016). The females of A. heraclei and A. spiraeana are readily distinguished by the punctation of metasomal tergum 1 ( LaBerge 1973).
