3 June 2007 New Brunswick Canada. 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. Tony T attached the following image: [121.21Kb] |

As nicely illustrated. In the Old World, unfortunately, the majority is of the lower type. Theo |
