We noticed that, it is  not only us interested in cowpeas at The 274Backyard, the guy below and his buddies were feasting on the cowpea beans on the pods.

The 274Backyard need to identify this guy and prepare for him before next season, any volunteers?

What pest affects your backyad and how to you treat it? Organic treatments encouraged. We hope it not Cowpea curculio!
