Black and yellow mud dauber (nest)

Sceliphron caementarium


After building a cell of the nest, the female wasp captures several spiders. The captured prey are stung and paralyzed before being placed in the nest (usually 6-15 per cell), and then a single egg is deposited on the prey within each cell. The wasp then seals the cell with a thick mud plug. After finishing a series of cells, she leaves and does not return. The larva spins a cocoon and pupates. Eventually, the hatching larva will eat the prey and emerge from the nest.


Spotted under hwy 7 bridge where it crosses the Caddo river in Caddo Valley, Arkansas.
