Although my pic isn't huge, these bugs are tiny, the marks can be seen quite clearly. They are here, this UK site has some hugely magnified pictures of Bruchus pisorum

This French site has even better pics which can be enlarged, the marks do match on Bruchus pisorum very well. There are the same white dots either side of the centre back with one larger at the top, a variable spot at the side of that shown on one pic. The blackish stripes either side of the centre back, white marks on the back above the hind legs, other black and brown blotches all in the right places.
