It is important inform you that, this guide is for illustrative purposes and non profit, in fact we want to give it and not sale. Our purpose with this pictoric guide is collaborate to beans producers to get learn and recognize more about the pests affecting their plantations and how they can use best environmental controls. With your permission, respective credits and authority will be added in this pictorical guide.

I would never have found mine if it hadn't been for the tell-tale folded leaf.

I raised what I think to have turned out to be a Platynota rostrana as shown here and here, but my caterpillar fed only at night, as far as I could tell, moving several inches from its home in a folded leaf to a healthy leaf (I judged its well-being by the droppings in the morning). Wanting to check the caterpillar's well-being after the folded leaf had wilted, I quickly stopped my intrusion when it tried to eject itself at the other end of the fold. You write that you "found" yours - was feeding at daytime?
