Bean weevils are generally compact and oval in shape, with small heads somewhat bent under.

Although their mandibles may be elongated, they do not have the long snouts characteristic of true weevils.

When ready to pupate, the larvae typically cut an exit hole, then return to their feeding chamber.

Adult weevils have a habit of feigning death and dropping from a plant when disturbed.

One characteristic of the beetles which can be seen in the photo is that the elytra are short, not quite reaching the tip of the abdomen.
