What kind of nest is this? Photographed in the lower level of the National Archives facility in College Park, MD - surrounded by woods on University of MM property. There are a lot if them and I have additional photos but could only load one here.

Prince George's County Maryland

From your photo this looks like a mud dauber wasp nest. The wasp is not aggressive. Knock down the nest if located in an undesirable area. See our Plant diagnostic Website for more information http://plantdiagnostics.umd.edu/level3.cfm?causeID=1031
