Sure, lots of fun pictures, but it isn't a truly "North American" field guide. A large number of insects are more for the Mid-West and Eastern U.S. If you are in the West, this book is thoroughly unhelpful. Also, there are many insects placed into categories, which to me, do not make sense i.e. things that LOOK like wasps are in the wasp section even if they are truly flies, butterflies, etc. For a field guide on insects, I prefer the Kaufman Field Guide to Insects of North America.
