They stick almost exclusively to parsley and dill, and are not likely to
move to your other plants. They will soon finish growing and crawl off to
pupate. Butterflies have a hard time of it these days, because of
widespread pesticide use, so I always gladly sacrifice some parsley when I'm
lucky enough to get the caterpillars.

Here's some more information:

i have some zebra-striped catepillars who are all over my parsley --
like
a
whole family just appeared one day and began camping out. they are
eating
the be-geesis out of the parsley, too. are they likely to move on to
other
plants? should i be concerned? should i pluck 'em off and git rid of
'em?

thanks for any help.
