ARGH!!! The dreaded SVB is back! I immediately went out and used a whole bottle of insecticidal soap on my vine crops, wiping the stems in case an egg had been laid. Then of course we had a huge thunderstorm, which washed it all away.
I'd never actually seen the moth before, and at this point I guess I can only continue to monitor the stems for eggs.
Any other ideas, short of suicide?
