Wasps of the World: A Guide to Every Family: 8

It is a good book. However, most of the information contained in the book is available on the internet. The word guide in the title of the book was a bit deceptive for me. A guide is generally expected to provide identification to some if not all wasp species. I wish someone brings out a photo field guide to the wasp species of the world or even of regions.Dr. Van Noort and Dr. Broad have done commendable work in bringing out this book.
