I think that this Sweat Bee (L. leucozonium) is a male since there's no pollen on its back legs.
Tech Specs: Canon 80D (F11, 1/250, ISO 100) + a Canon MP-E 65mm macro lens (under 2x) + a diffused MT-26EX-RT (E-TTL metering, -1/3 FEC). This is a single, uncropped, frame taken hand held. I'm holding on to the stem of the flower with my left hand, and resting the lens on that same hand to keep the scene steady.
