I found this little fella while camping. Looks awesome. I was suprised at my phones picture quality. This could be a common insect but I have never seen anything like it. I sorta examined it with a small stick and it had antenna like objects that protruded from the head at my stick. Left a pungent odor on the stick. I like the markings that look like eyes even though that’s not the head.

Tiger Swallowtail Caterpillar

Hi Toad,
We understand your weather is unseasonably warm, but we still suspect this prepupal Tiger Swallowtail Caterpillar is not a recent sighting.  The antennae you describe is a scent organ called an osmeterium.

  1. My mother discovered our dog was playing with what looked like mulch at first, come to find out it was a brown caterpillar. Later, we learned that it was a tiger swallowtail caterpillar. My cousin and I decided to keep it.
    We put it in a big jar with some grass, leaves, twigs and a drop of water. We learned how to take care of him until he turns into a beautiful tiger swallowtail butterfly.
    Finally, my question was how long does the caterpillar stage take? He/she looks like it is a full grown caterpillar. And we want to know when it will go into it’s chrysalis- then turn into a butterfly?

      There is no way of telling how soon the caterpillar will form a chrysalis, but it will probably be in the chrysalis stage for several weeks.
