FIGURES 1– 6 in Early nesting biology of the wood-nesting adventive bee, Lithurgus chrysurus Fonscolombe (Apoidea: Megachilidae: Lithurginae)

FIGURES 1– 6. Photographs of nests of Lithurgus chrysurus. 1. Woodpile of restacked firewood logs containing nests at Lehigh Gap Nature Center in Slatington, Lehigh Co., Pennsylvania. 2. Cell containing single egg from a series of cells, defined by partition of wood chips (egg accidently detached from provisions presumably resulting from jarring of wood as we attempted to split it). Note seam indicating division of disc from anterior cylinder of provisions. 3. Cell containing two eggs; note lack of partition between them. 4, 5. Close-ups of front and rear cells, respectively. 6. Cell from which fifth instar had been removed showing fecal pellet adhering to larval chamber and not mixing with provisions as in Lithurgopsis apicalis.
