Yes, I'd recommend it.
It hasn't helped me too much, because the butterfly caterpillars I find are in books I already had, like the Minno and Minno Florida Butterfly Gardening book and others. But if you don't have a butterfly caterpillar book, it's a good one, especially for that price.
Of course it doesn't have moth cats - my Caterpillars of Eastern North America by Wagner has proved to be a good one for moths.

Thanks, Sherry!

I'm up to my eyeballs in field guides, and was hoping that this would be a good one to get for a neighbor. He's been taking quite an interest in all of the activity in his own back yard.
