So we found 3 of these in the soil of our vegetable garden. In case location info helps, we live in Orange County, California about 4 miles from the beach and our soil has a lot of clay. The only things I’ve seen large enough to come from this are what are commonly called tomatoe worms here, or potato bugs. We saw a couple potato bugs in the garden last year but I haven’t been able to find any information about their life cycle, so I guess my question is two-fold: what is this chrysalis, and if it’s not a potato bug, what is the life cycle of a potato bug?
You have a pupa from the Tomato Hornworm, also known as the Tobacco Sphinx, Manduca sexta. The large green caterpillars you find on your tomato plants bury themselves in the dirt and pupate into the form you have dug up. They emerge as large moths, lay eggs and begin the cycle again.
