A few more pictures from that batch of caterpillars

They start off so small. (There are 2 eggs in the picture above)On their way to becoming eating machines.

Usually, the butterflies from the first batch of the year emerge around the beginning of July. As mentioned in the last post, we will often plant fennel for the purpose of hosting the caterpillars. It doesn’t cost much and seeing the new butterflies is definitely worth it. They (Black Swallowtail caterpillars) will eat parsley, carrots, dill and several other related plants. The ones in our area seem to prefer fennel.

One other interesting thing happened with the fennel. It grew back the next year. If the conditions are right it is a biennial or even a perennial. It was even bigger than the year before, but the caterpillars seemed up to the challenge.
