Both of the eastern black swallowtail chrysalis changed from green yesterday to brown today. Super interesting. Now they are better camouflaged against the wood of the butterfly house.

I now have two eastern black swallowtail chrysalis. I am kind of surprised they are green, rather than brown. Fingers crossed the butterfly emerges in about nine to 18 days.

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.
