black swallowtail
Hi, that is the Black Swallowtail Butterfly and it is beautiful. I always plant parsley and dill just so that I have these butterflies in my garden each year. You will enjoy them when they hatch out. Margaret
The caterpillar that is black with a lime green jacket is the Saddleback Caterpillar. These caterpillars can sting and it will be very painful.
which caterpillar is green with yellow stripes
Most catilppilars are green with black stripes but you may be looking at a Crossstriped Cabbageworm.
That's either a snake or a caterpillar. I hope it's a caterpillar.
Black or white stripes
A caterpillar that is green with a black spike at the end of its tail is the Puss Moth. They can be found in willow trees.
no, he is orange, with white stripes and black trim
You could paint it black or make it green and black stripes or white and green stripes. or if you really love green paint it green or just keep it white well you don't have to listen to me ask a friend.
Many caterpillars have a base color of '"lime green" - for instance the common tomato caterpillar is all lime green. The black swallowtail butterfly's caterpillar is lime green with black and a bit of yellow - see http://insects.tamu.edu/images/insects/common/images/cd-43-c-txt/cimg267.html
The black swallowtail (Papilio polyxenes) larva is the yellow caterpillar eating dill. The caterpillar stage of the butterfly in question prioritizes feeding upon the flowers and the seeds of such Umbelliferae family plants as carrots, celery, dill, fennel, parsley and Queen Anne's lace. The caterpillar ranges in color from brown-purple and white upon hatching to leaf green with black and white bands and yellow spots as later instars.
I think it's the Boomslang Snake
