So I found two caterpillars a week ago on my parsley and another on my dill and finally I found 2 more on my fennel. This is one that’s on my fennel. I’m so happy to be raising 5 caterpillars even if it’s a lot of work. I do have one chrysalis from last fall but the butterfly hasn’t emerged yet I’m hoping it will. This caterpillar is about 1/2 inch long and it’s past it’s first instar. The instar is the time when the caterpillar out grows it’s skin and sheds it. A normal amount of instars is 4 to 5 depending on the species of butterfly and moth caterpillars : )
