What's That Bug? does not endorse extermination

images of swallotail caterpillars on parsley
Dear Bugman,
just wanted to share a few more images, hope you don’t mind. all these are from last summer (2005). The swallotail caterpillars ravaged my curley parsley. (at one point i counted over 40 caterpillars of various sizes on this one little plant!!) after they were “full” some of them made cacoons on my purple fountain grass. anyway, hope you like the images!!
thanks for letting me share!

    I found these all over my parsley in Kissimmee, FL. Did not know if they were friend or foe. Looking forward to seeing which Swallowtail I have. How much parsley do they eat?

      If the caterpillars are eating parsley, they are Black Swallowtails. Males and females exhibit sexual dimorphism. If they have blue markings on the hind wings, they are females. Males have more pronounced yellow spots and lack the blue markings.
