Black Swallowtail Caterpillar

My 6-yr-old daughter found a Black Swallowtail caterpillar (also

called "carrot bugs", nearly 2" long) in her garden munching on her

carrots and decided to keep it as a pet. It's amazing how fast it can

devour a carrot leaf. Anyway, I've been playing with my 50-ish-mm

lenses and new extension tubes lately, so this was good fodder.

Putting it on a plant may have been more natural, but I think the

painted nails and fingertips add an interesting touch and a sense of

scale (never mind that she wouldn't have released her new pet under

any circumstances). Any suggestions for improvement?
