|Early instar of the Giant Swallow-
There are a Myer lemon and two Key lime trees in the back yard, potential larval host plants for the Giant Swallowtail butterfly. But a far-away small bowl of parsley did the trick.
The reddish-orange and dark brown caterpillar with a saddle of white (more white will appear with age) found the parsley patch just right for nibbling. Hooray!
