Black swallowtail caterpillar
by: Bonnie

I found a black swallowtail caterpillar in my parsley patch Sept. 2, 2011. He's really pretty and turns into a beautiful black butterfly with colored spots on the wings.

A black swallowtail butterfly flew up to your deck, laid an egg, the egg hatched...that is how the larvae got there. Unless you threw the caterpillar on more parsley, carrots, queen anne's lace weed or other related plants they will not survive. It will die.

Will they survive?

How did this black swallowtail larva get on my Parsley plants in the first place? They are in pots growing on a deck. I plucked them off & tossed them into the brush. I feel bad, but need my herbs & didn't grow them for the bugs to eat. Will they survive now?

Actually in OK you should have at least 2 maybe 3 generations of the black swallowtail so they should emerge in 10-14 days depending on weather!
Hope you get to see the butterflies soon!

Thanks for enjoying this cool part of nature!

Not sure why you brought them inside...they do fine out in the garden. Mother Nature knows how to best take care of them.

Well, Anonymous was correct it is sometimes called the parsley worm, as well as - Eastern Black Swallowtail,Parsely Swallowtail,Dill Worm, Parsley Worm, Celery Worm,Carrot Worm, Fennel Worm.
The common name depends on what plant someone sees it feeding on.
Larvae feed primarily on plants of the carrot family and some in the Rue Family . It is usually found on Dill, Parsley, Fennel, Carrot, and Rue in gardens, and Queen-Anne's-Lace, Poison Hemlock, and Lovage in the wild. The caterpillar will stick out smelly orange "horns" to prevent predators or us from picking them up.
It overwinters as a pupa.

The adult butterfly is black with yellow spots for the male and yellow with blue spots for the female. They are a common garden butterfly.

And the winner is...
