Patiently, I photographed this patient bee for over five minutes, on this same flower. As the flower waved in the breeze, it was motionless with respect to the flower, Pollen coats its legs and dusts its antennae, head, and back. I can see two large compound eyes and three smaller eyes in between -- compound eyes for detail and for browsing, smaller eyes (ocelli) on top for evading predation, for fast reaction time?? As often happens at this scale, hairs cover the fly's body and legs. Thanks to Pierre Martineau for the ID. He writes that this "is actually a bee, not a fly. The 2 telltale characters are the antennae and the wings (the second pair of wings is very hard to see but if it had been a fly, we would see the halteres). The 3 small simple eyes are called ocelli." 4/5/2018, 1:11 pm.
