Cicada killer wasp
Sphecius speciosus
- Order & Family
- Hymenoptera; family Crabronidae
- Size
- Adults are typically 25–50 mm (1–2 in) long, with females larger than males.
Natural Habitat
Open, sandy or loose-soil areas, including lawns, gardens, roadsides, and forest edges, where females excavate burrows.
Diet & Feeding
Adults consume nectar and may feed on plant juices. Females capture cicadas, paralyze them, and provision underground nests with them for their larvae.
Behavior Patterns
Solitary rather than colony-forming; adults fly in midsummer. Females drag cicadas into branching burrows, lay one egg per prey item, and males may patrol aggressively but cannot sting.
Risks & Benefits
Females can sting if handled, but are generally nonaggressive toward people. They help regulate cicada populations and pollinate flowers; their burrowing can disturb small patches of soil.
