What eats beet greens and chard?
This is my first year gardening, and I recently looked at my beets and chard after a week (we were on vacation and had someone else watering), and some of the leaves are skeletal! Most of the beet leaves are gone, and it looks like whatever it is is just now starting on the chard. I can't find any bugs on the leaves, even in the evenings. They're basically being munched in between the leaf veins, leaving a skeletal remainder. Any ideas what this pest could be?
