Swallowtail Caterpillar (Pterourus glaucus)

As a follow-up to my prior post of the beautiful Swallowtail butterfly, the fennel in the pot on my deck is now covered with these attractive Swallowtail caterpillars. The photo doesn’t fully capture the vibrant contrast between the black, white, and green stripes and the iridescent yellow spots that make these caterpillars even more flamboyant than the monarch caterpillars (pictured in a prior post).

  1. How good to know it finally what this animal is! If I see well, it is on a fennel. At us it goes mad for the fennel. It is so wonderful animal that although it devored a lot of fennel, I did no harm to it. I’m happy of having done so. Your image is very attractive!Kata
