What's That Bug? does not endorse extermination

Dear What’s That Bug,
I was walking through the woods yesterday evening when I ran across several of these creatures. We live in the southeastern U.S….these were found near dusk in a drizzle in a forest. I have always heard of them being called ‘cherry bugs’ due to the scent that they emit when startled or feel threatened…they are between 1.5 and 2.5 inches in length, black, with yellow spots down not only the sides, but also down the center of the back as well. All markings are symmetrical. They look *very* similar to a picture I saw of a yellow-spotted millipede…the difference being the extra row of yellow spots down the center of the back….plus, the yellow-spots are from Oregon…and we are in Tennessee. I am curious to know what exactly these are, they are interesting creatures, and I’d like to know a bit more about them. Also, any care advice would be appreciated as well.
Thank you! –

Dear Christina,
Unfortunately, if you enclosed a photograph, it did not arrive. Based on your description, and your latitude and longitude, I would guess that you have stumbled upon some caterpillars, more specifically, the larvae of some local swallowtail (Papilio sp.) My guess would be the larvae of the black swallowtail butterfly, which feeds on parsley and related plants including Queen Anne’s Lace which grows in uncultivated meadows. The caterpillars are green, black and yellow, and have two orange horns which are hidden near the head. When the caterpillar is threatened, the horns emerge, along with a musty smell that I would not really liken to the scent of cherries. Try this: http://www.ivyhall.district96.k12.il.us/4th/kkhp/

If you keep them in captivity, you can feed them carrot tops. They will form a crysalid and a butterfly will eventually emerge.
