I have several grapevines in backyard here in Las Vegas. In the last
week or so I have noticed that the leaves on them are are being eating
very voraciously by caterpillars. They are yellow with black bands.
The link below has a photograph of one of them I took today. Any
recommendations on what to stop them with?
Sounds like the Western Grape Leaf Skeletonizer. The adult phase is a small
dark blue moth which resembles a wasp with feather like antennas. The
caterpillars are yellow, and blue striped that feed side by side eating the
leaves leaving only the veins. After manually picking off and destroying
the caterpillars and any eggs, the recommended control is a Bt spray. Do a
web search - there is a lot of info on this.

water, but I'm guessing you wanted something less labor
