Agenioideus humilis
Spider Wasp
Agenioideus humilis is a small spider wasp in the family Pompilidae that hunts orbweaver spiders (Araneidae) as prey for its larvae. Females paralyze spiders with their sting, then transport them to nest burrows where a single egg is laid on the immobilized host. The species ranges across most of the United States but is considered scarce throughout its distribution. It favors woodland habitats with sandy soil and has been observed nesting in both excavated burrows and pre-existing cavities such as rock crevices and building cracks.
