Black Mud Dauber
Scientific Name: Sceliphron caementarium
Order & Family: Hymenoptera: Sphecidae
Size: 24 to 28 mm (approximately 1 inch)

Natural Habitat
Open areas near muddy soil, often found around human structures like eaves, bridges, and barns.
Diet & Feeding
Adults feed on plant nectar; females hunt spiders (especially orb-weavers) to paralyze and provision their nests for larvae.
Behavior Patterns
Solitary wasps that do not form colonies. Females build tubular mud nests, stock them with paralyzed spiders, lay a single egg, and seal the cell. They are non-aggressive unless handled.
Risks & Benefits
Benefit: Provide natural pest control by hunting spiders. Risk: Rarely sting humans unless provoked; the sting is painful but generally not dangerous unless the person is allergic.
