Heriades carinatus, m, back, MD, Prince George's Co

A small thin well armored bee. Just so to fit in the abandoned burrows of powder post beetles and the like. Obliquely related to Mason bees, the females carry pollen and are notable for their use of plant resins to plug their nest holes. This one from Prince George's County. Photograph by Elizabeth Garcia.

A beautiful little hole nesting bee, this Heriades is either H. variolosa or H. leavitti. The females are impossible to tell apart, unless the molecular hood were open. Collected on Chino Farm by Dan Small in Kent County, Maryland. Photograph by Brooke Alexander.

Dieunomia nevadensis, M, Back, MD, Upper Marlboro

A very cool find. This is a lovely male Dieunomia nevadensis. It was found in Maryland at one of the Chaney Sand Mines. They kindly scraped a section of the site and sure enough it was colonized by all sorts of cool sand bees. No sand...no sand bees. That sort of thing. This one is particularly noteworth because the nearest record was from North Carolina.

Here is a 2 picture series of persimmon (Diospyros virginiana) flowers. Some trees are male (staminate) and some are female (pistilate). The easy to come by literature of the web searchers says they are pollinated by insects and the wind. I have never collected off them (too high up and am guessing not super attractive to bees).

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.
