Sceliphron caementarium
They are solitary insects that build nests out of mud, in sheltered locations, frequently on man-made structure such as bridges, barns, open porches or under the eaves of houses. These nests are not aggressively defended, and stings are rare. The black and yellow mud dauber's nest comprises a series of cylindrical cells that are plastered over to form a smooth nest that may attain nearly the size of a human fist. After building a cell, the female wasp captures several spiders. The captured prey are stung and paralyzed before being placed in the nest, and then a single egg is deposited on the prey within each cell. The wasp then seals the cell with mud. After finishing a series of cells, she leaves and does not return. Eventually, the hatching larva will eat the prey and emerge from the nest. There are some 30 other species of Sceliphron that occur throughout the world.
Seen near flowering gardens.
Seen this nest a day before and my guess is, the nest belongs to this dauber: http://www.projectnoah.org/spottings/102... details from wikipedia.

Thanks. The line does seem like a spinal cord :-)
delicate beauty!! The line seems to be like a spinal chord.
And the line seems to be very thin too.
very unusual and delicate body structure!Just a line which connects two segments!
Yes, Emma. I did check and guess that the nest belongs to this dauber.
yup,the nest you put up in your previous spotting probably does belong to this insect.
