~Say What?!?~ 062111

Somebody is busy chomping my radishes. Any ideas on who it could be? Any suggestions about how to conquer them? Interestingly enough, they aren't bothering the radishes themselves and we haven't jumped into the world of eating radish greens. As a result, these little pests are leaving us unscathed for the most part, but I am worried about the damage they might do elsewhere in the garden. Thanks for your suggestions!
