We have found a caterpillar which is new to us! It was apparently in a hurry to pupate, as soon as we housed it, it went to work. I think Mom is having the most fun here! 🙂
We are in the north central (Brewster) part of Washington State. This is a darker bluish green caterpillar with white and black eye spots and white and black collar. It turned to brown very soon after we found and housed it.

Dear Elizabeth,
We believe this is a Western Tiger Swallowtail Caterpillar, but we would not rule out that it might be a related species like a Two Tailed Swallowtail Caterpillar.
