Thanks!
Hmm...
For me, of course, they "look the same". I shot all three of them without moving (the time difference in EXIF is 3 minutes between the pictures). Apparently, this happens.

visible difference in the color of 2-4 tergites and hind legs, there should also be differences in the color of the platypus, in the number of flagellar segments and, most importantly, in the degree of development of the hypostomal roller at its confluence with the occipital one.
And the views, of course, are very close

PS I never get tired of wondering how you manage to meet so many things, and I also try to shoot everything decently

. Sometimes I try to find riders for a photo shoot, but something is clearly wrong with luck. And about the results of the shooting itself, when something happens, I just won't say anything

, they don't like to pose for me

Yes, too, there are not so many riders and, as a rule, even in the morning hours they are quite active and can not stand shooting. All that can be removed is in the early morning, and now at night, while the insects are sleeping. Without a macro flash with a diffuser at a minimum ISO, micro-oil is provided at the slightest movement. All macro photography is a constant compromise!

something I can't determine before the appearance of this ectemnius.
about 12 mm. The 3rd part of the sawyere is slightly longer than its width, less than the 2nd part. The top of the platypus is in the form of a platform, slightly concave in the middle, without side teeth. Unfortunately, you can't see the inside of the mandibles. Midrib in very thick, rather rough dotted line, without longitudinal and transverse wrinkles. The transverse keel on the mid-chest is weak, only from the sides. The sides of the mid-chest are shiny with sparse but clear dots. tergites are quite dense, but finely dotted. 1st tergite in a rarer dotted line, shiny.
I would have assumed that nigritarsus, but according to the photo in the Internet, the color of the abdomen is completely different.
