Conclusion

My conclusion is that pumpkin can be used as a subsitute food for a limited time period. The reason for this is because I had almost half of the caterpillers die, plus two crysilis die. I still have 10 crysilis none have hatched yet.But I have found that the caterpillers still prefer the swan plant (milk weed) but will eat the pumpkin when necessary but not as a sole dietry food.
