Wasps known as mud daubers...
Mud daubers are a variety of wasp which build their nests out of mud or use the nests of other species of wasp. Mud daubers which survive the cold months are immature individuals which spend the Winter in the nest.
The scientific name for a dirt dauber is Sceliphron caementarium.
Mud daubers are solitary wasps, so it is very unlikely that they will sting you (unless you do something like trap one in your hand). Unlike hornets and yellow jackets, mud daubers do not defend their nests.
