This was the first year I found several monarch caterpillars in the yard. After finding and exploring the website, I decided to purchase the print book for handy reference. I love this book! The paper, printing quality including many photos with amusing captions, and layout are excellent. It's extremely easy to read, well organized, includes much of the basic information from the website, and is a delightful reference for beginners. I can also use it to easily show friends of all ages my new hobby. My shipment arrived quickly and in perfect condition.
