Masked Bee from Dorchester County. An alien masked bee, Hylaeus leptocephalus to be exact. In Maryland (in this case, Cambridge, Maryland) it is almost completely restricted to the urban weedy lot and industrial tract. Railroad lines...the best. Photography by Amanda Robinson.

Hylaeus ornatus is a masked bee, one that is always associated with wetlands. These wetlands can be freshwater marshy spots or they can be the backsides of salt marshes. Almost all have lovely red basal portions of the their abdomen. Some do not. We have series of these bees in a DNA lab to see if these two groups are different or the same.

A wetlands bee, usually with red on the basal segments of the abdomen but not always. The males with extensive yellow on their faces. Here from the marshes of Kent County, Maryland

Colors. You know, bees are so interesting sometimes. Here is Hylaeus pictipes. Jason Gibbs found this species up in Ontario, Canada where it did not belong since it is a bee of the Old World.
