Gen: book on butterflies

[Florence Mcelligott <Fmce@AOL.COM>]

Anyone know of a book - nonfiction - which would have identification of
butterflies showing caterpillar stage and what the caterpillar eats?
Many times children bring a caterpiller in to be identified and it sure would
help.
I haven't found one yet which has the three things -
larval stage, caterpillar and food.
If there is, I'd like to get title.
If not - an idea for an enterprising writer?
Not me, I'm an appreciative audience!
