A very useful, and convenient, character for identifying female Chrysops spp. is the absence (top image C. calvus)) or presence (bottom C. mitis) of a yellow pollinose stripe on the clypeus. These character states readily divide the North American spp. into 2 more manageable groupings.

Well it should be compared to the insect diversity and numbers of that region for the last years/decades...
