Chrysalis on fennel plant
We had tiger swallowtail caterpillars on our fennel plants recently and I noticed this chrysalis last night. How long until it hatches? I love your website, I’ll definitely be sending pictures in for identification. This was taken in Clayton, North Carolina, August 1, 2005

Hi Ken,
This is definitely a Swallowtail which is recognizeable because the crysalis is upright and has a support strand of silk around it. Not a Tiger though since fennel is not a food plant. In your area, I would guess a Black Swallowtail which feeds on carrots, parsley, Queen’s Anne Lace and related plants. I am not sure if the Anise Swallowtail ranges in your area. That would be a first choice in the West.
