Predating Plains Cubtail
No strike, the surface pair split when the predator noticed what was happening beneath
Had been paused along the west branch for some time, admiring the thick vegetation in a still pool near a downed tree with three trunks crossing the stream (just N of the mid cut), brought the bins up to scan the vegetation and saw a blur come across FOV. Darner remained, hovering often in one place for 10-20 seconds. My first Shadow Darner, perfect setting and grateful mindset for the encounter.
