Abstract

Ptilothrix bombiformis (Cresson) nests in hard-packed roadways and levees along Delaware coastal marshes. Nests contain 1 or 2 wax-lined cells. The spherical pollen-nectar mass is from Hibiscus palustris L. The egg is located on the bottom of the provision. Overwintering is as a post-defecating larva. The nesting biology of P. sumichrasti (Cresson), P. plumata Smith and P. fructifera (Holmberg) is compared to P. bombiformis.
