Alien being? - Papilio glaucus

Alien being? - Papilio glaucus
near Dexter, Washtenaw County, Michigan, USA
August 5, 2005
Size: approx. 1.5" long
This was found on our garage floor today. It stuck it's tongue out - it was forked. The "eyes" may not be actual eyes but may ward of predators? I have other pictures as well. But the creature is back in the woods.
Very strange.

I should have perused before asking. It's an Eastern Swallowtail caterpillar - of course.

not a tongue
I've seen that forked "tongue" before too. It's not a tongue, but rather a sort of proboscis that gives off nasty chemicals meant to repel predators, for those occasions when the big scary eye-spots don't work.

forked "tongue"
Yes Joshua, it did smell awaful when he stuck it out. lol He was pretty "bugged" by then, I'm sure.

Osmeteria of different swallowtails can be seen at and at

Thanks for the reply.
It's a wonderful world!
