I have roughly 18 caterpillars that have survived and they are doing well! They eat like there is no tomorrow and doing plenty of poops! They have almost doubled in length, so growing fast now. I will have to find a bigger box as they may soon be too big for the Egg Fried Rice box that they are in now! No expense spared in the rearing of caterpillars.lol!
I have attached a link that shows the development stages from egg to adultHere.
