Two of the eastern black swallowtail have found their spot in the butterfly house to start their next stage, the chrysalis. The other two caterpillars are still munching away on the dill.

It appears that the caterpillar below has its silk girdle done, which supports their chrysalis. The silk girdle, or band, is around the thoracic leg area towards the front of its body. The end of the caterpillar is attached to a silken pad. These caterpillars too will mimic the color in which they attach their chrysalis. So, they should be of a “bark” like color when they are done.
