About Megachile melanophaea Smith, 1853
Females of Megachile melanophaea measure 12 to 14 millimetres (0.47 to 0.55 in) in length, while males measure 9 to 12 millimetres (0.35 to 0.47 in). The head is black and covered with brownish-black hairs, except the lower part of the face and the base of the antennae, where hairs are yellowish-white. The thorax is densely covered in hairs, with yellowish-white hairs on its back and sides, and brownish-black hairs on its underparts and the legs. The wings are translucent, with brownish-black veins. The first two dorsal abdominal segments, called terga, have erect pale hairs, while the rear terga have erect black hairs. The scopa, the pollen-carrying apparatus located under the abdomen, has reddish-brown hairs. This species is native to North America, with a range extending from Nova Scotia to British Columbia and Alaska.
