Black and Yellow Mud Dauber
Sceliphron caementarium
39.9356, -75.1465
Field Notes
Description:
Black body with variable amount of yellow markings. Pedicel (waist) about twice as long as the rest of the abdomen.
Habitat:
Mud nests are built in all kinds of sheltered locations, incl. man-made structures, rock ledges, etc. Adults collect mud for nests at puddle/pool edges.
Notes:
Nests are provisioned with spiders; adults common at flowers. Nests may comprise up to 25 cylindrical cells, with typically 6-15 (up to 40) prey spiders per cell. The female may provide the cells with a temporary closure (a thin mud curtain) to keep out parasites while she is collecting prey. Once the cell is stocked, she lays an egg on one of the last prey and seals the cell with a thick mud plug. She may then add more mud to cover the entire cluster of cells.
