Hylaeus (Metziella) sparsus (Cresson 1869)

County records: Dickinson, Ingham, Jackson, Midland, Washtenaw.

Notes. This is a rarely collected species with a relatively broad distribution across eastern North America (Sellers & McCarthy 2015). Hylaeus sparsus has been collected from several plant species, but it has been suggested that it prefers flowers of the family Apiaceae (Sellers & McCarthy 2015) and a recent record from Brooklyn in New York City (3 Jun 2012, Prospect Park Wellhouse) was taken on that host family (JSA, unpublished).
