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.

Thanks to everyone

Grabdornen, surely spines on the cerci for egg-laying in soil or sand?

14.11.14 11:00
graben -> to dig. First request was for Grabdomen which is 'burial dome', LoL.

14.11.14 10:36
The literal translation of Grabdornen is grave (Grab ) thorns (Dornen). I think the best English translation is "spines".

13.11.14 16:42
Legrohr am Ende (cerci) mit kraftigen , nach oben gerichteten Grabdornen

13.11.14 15:46
