I am in New Orleans, La. I hadn't grown beans in a long time. I have
grown mostly okra, tomatoes and peppers and had never seen this kind
of pest. These worms are very small, not quite 1/4" long, have a light
colored body and a darker head. The best way that I can describe the
damage is if you took a scissors and made small snips at various
distances along the edge of the leaves and then turned the flaps back.
Maybe someone knows the name of this pest. I searched under "pests of
beans" but could find nothing.

Though I've never read about such on beans, that certainly sounds like the
action of some type of leaf-rolling caterpillar, for which Bt (Bacillus thurengiensis,
sold under various brand names) would be a safe and effective control if hand
picking is impractical.
