Likely spider wasp (tarantula-hawk type)

Open, warm habitats such as deserts, scrub, and gardens; often seen walking on the ground or around buildings.

Adults feed mainly on nectar and other plant sugars. Females hunt spiders, which their larvae consume.

Females paralyze spiders and lay an egg on them; adults are solitary and often have conspicuously long legs. The image is not clear enough to confirm the identification.

A female’s sting can be extremely painful but is not generally medically dangerous. They help regulate spider populations and pollinate flowers.
