I'm with Robert; cropping out the two darker stems(?) from the bottom helps. Perhaps just cropping to the top of the left one and then masking out the rest of the one near centre would work too, leaving a bit more of the leafy green. Too bad the blighters always land on the wrong flower and you end up with one OOF in the foreground. Nice that you were able to hold enough depth of field to get the fore wings and body sharp despite being wide open.
