Thread-waisted wasp (likely great golden digger wasp)
Sphex ichneumoneus
- Order & Family
- Hymenoptera; family Sphecidae
- Size
- Approximately 20–35 mm (0.8–1.4 in) long.
Natural Habitat
Open, sunny habitats such as sandy soil, gardens, roadsides, prairies, and woodland edges, mainly in North America.
Diet & Feeding
Adults consume nectar and sometimes honeydew. Females provision underground nests with paralyzed grasshoppers and katydids for their larvae.
Behavior Patterns
Solitary and generally nonaggressive unless handled; females excavate burrows, stock individual chambers with prey, and seal them after laying one egg. Adults are active in warm weather and often bask or forage on flowers.
Risks & Benefits
The sting can be painful but this species rarely stings without provocation. It benefits ecosystems by pollinating flowers and suppressing grasshopper and katydid populations.
