The description fits perfectly, but the appendages are not visible. It is quite obvious that it is Aciagrion, but not A. gracile. There are apparently no other options for this area. Also a photo of this dragonfly with discussions: https://www.inaturalist.org/observations/148445031

I need your help. I can't figure out who it is. There is an assumption that there is also some kind of Aciagrion. But the abdomen is noticeably shorter than that of A. gracile and the dragonfly itself was smaller. Merlot Park, a reservoir devoid of any coastal vegetation. This dragonfly kept grass 1-2 meters from the shore together with A. gracile and Ceriagrion glabrum. While there is tolkyo this photo. Perhaps it will be even when I get to the photos from the camera. Any ideas? And could it be some form of A. gracile?

These brine shrimp live on top of a huge boulder/rock, the water that they live in is only there for a small amount of time. There were also extremely small black thing that could have been young ones or a different kind? They are a reddish brown colour on the body and they have a peacock eye on their back.
