From my experience, you have done well to get so close with 90 mm. I frequently struggle with twice that length.
Possibly a tiny touch more carefully controlled use of Curves might work. And maybe the same with selective sharpening on the fly; but very little.
Sometimes I can get away with drawing a freehand selection roughly around the subject, and feathering by about 5 pixels, then applying a little Unsharp Mask; perhaps 80% 1 pixel and 1 level of threshold. After which I apply more Unsharp Mask to the whole image, to suit the background. This gives a bit more 'pop' to the insect and is easier than attempting to use layers and masks. Although that method still remains the correct procedure for many difficult circumstances.
