Suny,

I do think we have the same problem. I've seen this for years now and it seems to be getting worse. Not sure if leafhoppers are "bad" but the crud left on the plants looks "bad". You are correct on hostas too - the bloom stalks. Guess I've been paying more attention to my hydrangeas this year along with the lilies (which are almost over for this year - boo hoo). At least next year I can start a spraying program earlier on not only for leafhoppers but some kind of worm chewing massive grids in my hardy hibiscus and rose of Sharon bushes. GRRR!

I never heard of diatomaceous earth for leafhoppers but have seen it advertised as an organic way for controlling slugs and snails. I bought the D.E. for swimming pools and used it at our last house - seemed to be a huge waste of time. Not sure if there is a huge difference between D.E. for slug control versus D.E. for swimming pools. I'd stick with Neem, insecticidal soap, or any other insecticide for that matter.

Here is one that must've escaped the spray from yesterday on the backside of Alocasia 'Sarian'. Looks like an alien life form.
