Sand Wasp (Bembix americana) Total length: 2 cm Buried within the sandy cliffs and ledges, female Sand Wasps (Bembix americana) dig miniature nest caverns to rear a single larva; provisioning them with captured flies and other insects as they grow. The adults of this solitary wasp species also feed on floral nectar and provide pollination service along the way. Sand wasps of different subspecies are found ubiquitously throughout the United States inhabiting sandy habitat. Most sand wasps are yellow and black and often have a banded pattern with hints of green color. These small insects are not social like other wasps and can be found digging sandy caverns to protect their eggs. They hunt for various food, including flies and mosquitoes. Though they are capable of stinging, they almost never sting humans unless provoked. Cabrillo National Monument, San Diego, CA USA
