sphecid wasp
Quick Summary
The Sphecidae, commonly known as thread-waisted wasps, are a family of solitary wasps belonging to the order Hymenoptera. These insects are characterized by a slender body and a narrow "waist" connecting the abdomen to the thorax.123
Thread-waisted wasps are typically predatory or parasitic. Females hunt insects or spiders, paralyze them with their sting, and then place them in a mud cell or burrow to serve as food for their developing larvae. Different species specialize in various prey, such as caterpillars, spiders, or cicadas. For example, cicada-killer wasps (Sphecius) are known for hunting cicadas to feed their young.245
While most wasps are solitary, the Sphecidae family includes diverse nesting habits, with some building mud nests and others digging burrows in the ground. These wasps are generally not aggressive towards humans, though females can sting.435
