Alternative foods for grapevine beetles, Pelidnota punctata

[pickle01]

I'm lucky enough to live in an area with plenty of wild grape and Virginia creeper available, but I'm curious if anyone has found other plants that grapevine beetles will eat. I have tons emerging right now from some pairs I bred a couple years ago, but before I offer any for sale I want to make sure people can feed them easily. I've read a source that says they'll eat spinach but mine didn't touch it.

I collected and reared probably about 1,000 of them.. I fed my beetles grapevine leaves mostly, as I had some plants growing at my yard. Other than that, I tried some fruits and beetle jellies which worked fine. Never really tried on feeding other plant materials, as I already had full of grapevines..

I hadn't actually even thought of trying jellies, but I'll see what they think. Thanks!
