The ones here feed on grape leaves so I would go and pick some grape vines (everyday-fresh ones)-put them in water and put the caterpillar and fresh vines in a net cage. Make sure you cover the water container around the stems with plastic or tin foil-so the caterpillar doesn't fall into it and drown. Use soil around the bottom of the cage-slightly-very slightly moist. When theyare ready they go to the ground dig a depression and pupate-and then you wait.

Now the one thing I'm not sure about is if they wait till Spring to emerge-as I have one that seems fine-but hasn't emerged yet.

I learned all that from my mistakes before. But raising the caterpillar was easy.

I noticed you currently have the same date on each one, but I'm guessing that's just because you submitted them all together - are you able to edit to show the actual dates for each image? It would be interesting to see how long this took.
