...but not without errors Smile Only the abdominal tergites are visible in your photo - in this case the tergites cover also most of the ventral side of the abdomen. And I think area 9 isn't really the propleuron, which is between the anterior spiracle and the neck.

kahis, I was seeing again the photo, and I must disagree a little with you. We can see a little of sternites as well because the fly is slightly tilted! What do you think?
Concerning area 9 you are right, but then what is that region? Please let us know! Smile Thank you.

Any more opinions will be wellcome. Smile

Kahis is right. In tachinids the tergites wrap right around and the sternites are small or you see very little of them, even with a ventral view. I think you were fooled by the change in the pattern which must be caused by different dusting (different sized scales giving different reflections maybe ?)

yes, Susan. You must be quite right! Perhaps the different sized scales fooled me.. or another. Wink

So, there are just 2 errors. Not bad. Wink Let's go. I'm waiting for bigger photos of these fly! Smile

Ventro-lateral view showing the "wrap-around" tergites.
