Broad bean seed beetle is a pest of the dry seeds and is most likely to be seen by gardeners who save their own seed.

The adult insect is a small beetle that belongs to a family of seed-infesting beetles that are known as bruchid beetles. It is the larval stage feeding inside the seeds that causes the damage.
There is no control available to amateur gardeners. Fortunately, affected seeds will usually germinate as the grubs feed in the cotyledon part of the seed, most of which survives, and the seed embryo is undamaged.
