Found what appears to be a tomato hornworm in Phoenix. It is really cold outside. The kids want to keep it and try to observe it mutating into a moth. We know that it burrows so we need dirt, but what does it eat and does it need water? We found it in a yard of a friend. Not sure what to do with him. Thanks. L
There are many hornworms, and without a photo, we cannot properly guide you to the proper food plant. If the caterpillar was found on the ground, it is most likely ready to pupate and the food plant is not necessary.
Thank you so much. We let him go in hopes he would dig in. It will be freezing this week and didn’t want him to die. Thx
I will send you a pic
Hi again Lisa,
There isn’t enough detail in your photo to be certain, but this is not a Tomato Hornworm. We suspect it might be a Great Ash Sphinx Caterpillar, Sphinx chersis, and you can compare your photo to the ones posted on Sphingidae of the Americas.
