There are several of these on my Lima bean plants. They do not try to escape when approached. I think one was chewing on a new bean pod. On pic is juvenile and one more mature.
Having Assassin Bugs on your bean plants would be beneficial since they are predators, but your insect is an herbivore, an immature Katydid. Katydids will eat leaves, and in our garden, they also eat rose petals. Katydids are generally not numerous enough to present a problem. Since you do not eat the leaves on the bean plants, and since loss of a few leaves will not negatively impact the yield of your plants, you probably do not need to be concerned.
