I was at the LA County Arboretum last weekend and noticed a couple of these flitting around next to a little stream. I waited for a while before one landed on a reed. Cropped about 50%, as I don't have extension tubes, at least not yet. Cloned out one OOF blade of grass at the bottom of frame.
I posted a processed version in OOTB yesterday.
