I was out weeding around a poor abused young grape plant, and I dug up a little white grub. Remembering you guys singing praises of those little plastic cups, I went in to the house to grab one to scoop it up in. I'm fairly certain that it is just the grub of a pesky june bug, But I was wondering if you fine folks could tell me anything more about feeding it. I made sure to take some of the dirt it was grubbing around in, as well as some bits of roots from the weeds, which I have always been told that they eat. However, I looked online and it mentions that it's the adults that do the damage to the crops. So I guess what I'm asking is if it even needs food as a larvae and if so, what I should be feeding my captive. Thank you in advance all.
