This is a female Hylaeus (masked bee), measuring 7.25 mm, found on Pyracantha.

This is a largely black bee, with a partly-red abdomen, and yellow markings on the face, pronotal collar and pronotal lobes. The bee’s tibae, basitarsi and tarsi are mostly orange, with some yellow on the upper/basal hind tibiae. The apical (rear) half of each of the bee's forewings is dark. ABDOMEN: The bee’s abdomen is glassy and mostly black. These parts of the abdomen are red: the first segment (T1 and S1); and the basal 2/3 of the second segment (T2 and S2). Most of the remaining abdomen is black, except for narrow red areas at the bases of S3-S5; and a small central area of S6.
