they will start to look kinda dirty when they are done feeding. Not sure how else to describe it. They start to lose their features slowly and turn a litte dark on the ends. I used to think this was them going bad so I chucked my hornworms at that point but as long as they are around 3", they will dig once you quit feeding them. It might take a couple days and you might have to put them in the bin several times until they finally dig and pupate. I have had them pupate lying on the soil of a plant before without digging as well. These things are not difficult at all to breed as I previously thought. Much easier than silks IMO.
