I've recently just planted my first garden here in Nevada and it is already under attack. For some time, something has been slowly but surely eating away at 2 leaves on my zucchini. It has been eating just a little every day for about two weeks and has finally almost finished off one leaf. I'm getting zucchini starting to show, and whatever is eating the leaf has moved to the actual vegetable. I can't begin to figure out what is doing it. Too small for a rabbit. Too localized to be insects. No signs of worms. Lizards??? Any suggestions would be greatly appreciated.
