So I'm fighting battles with various pests. Some I catch in the act -- I've found caterpillars hiding under leaves of my broccoli, and golden beetles hiding under leaves of the sweet potatoes.
But some, I can't catch in the act. I'm having something eat the leaves of my bell pepper plants, but I can't find anything on the plant, or under leaves. It also seems to be affecting only the top leaves, and the plant is getting fairly tall (14" or so).
I guess I'm assuming something like slugs would start at the bottom leaves? I thought maybe it's something flying, but do any flying insects land on a leaf, eat fairly large holes (penny sized), then fly away?
And not specific to this specific problem, what kind of things clue you in on what you're dealing with when your accessing damaged leaves?
