I don't see any webby stuff, or any mites through a magnifying glass, but I'm not entirely sure I'd know what I was looking for. I wiped the leaves with some insecticidal soap and will hope that takes care of things. Agh!
Not sure if you would see mites with a magnifying glass unless it was magnified at about 500 times. They are very small on the digital microscope.
Heh, I'm still not sure what caused the leaf damage, and the new leaves and new cane look fine, but I was just startled to find a little friend on the plant! Hopefully he'll eat any pests hanging around....
