Can anyone identify this bug or the weed they're living on? I'm sorry the pic isn't any sharper but no macro lens on my cellphone. They're a bit bigger than an aphid, but black and look more like a beetle. We have several of these weeds growing along the fence line and ever one was covered with the bugs near the flowers. We did not find them on any other plants, but I'm afraid we'll end up with them on our vegetables. Any suggestions?

The weed looks like shepherd's purse, Capsella bursa-pastoris.

My guess would be aphids, but can you knock some off onto white printer paper and try another picture, then the phone would focus more on the bugs? Or, if you have a magnifying lens, take a look at their rear ends for two "tailpipes" (cornicles) which would identify them as aphids.

Figure 2 here has a picture of cornicles:

Thanks, @sooby. Shepard's purse appears to be what we have. We sprayed the bugs but I haven't checked to see if they're still alive. In looking at them, they don't look like any aphids I've ever seen. I'll check in the morning and see if I can get a better picture of them.
