Like Philanthus, Bembix also captures insects, digs and covers holes and lays eggs on insects they store in the holes. Some Bembix species continue to supply insects to their developing young after hatching. They sometimes occupy the same sites as Philanthus. In photos, the pseudopupil makes Bembix appear to be peering at the camera.
Bembix can be identified by the stout body with white or yellow stripes, close-set antennae and an elongate proboscis. Like Philanthus, Bembix digs with its front legs, which have special adaptations for digging. In covering a hole, Bembix can excavate at least a ten-centimeter-long oval. Bembix adults generally feed on flowers, but see Bembix adult feeding.
