Most helpful critical review
Solid primer, somewhat awkward field guide
on November 22, 2000
This book provides perhaps the best available set of basic instructions for butterfly watching. As some of the other reviews mention, it's not just a field guide; it's also a very thorough and pleasing introduction to how to go about the hobby. What type of binocs to choose (close focus please) is, for example, the sort of basic thing it covers well.
That being said, Butterflies through Binoculars shares a lot of the same traits I find mildly frustrating in the current set of Audubon's bird guides. It uses photographs, which I've always found less useful than thoughtful artist's drawings in my bird books. All the plates, moreover, are stacked together in front of the book. Maybe others find it handy to flip through pictures only, but I'd much rather see things like the better bird guides do it: color plates on one side, succinct species description with range map on the other. Whenever I use a guide like this in the field I end up flipping back and forth in my field guide like I can't make up my mind.
For that reason, I'd recommend this as an introductory title, but I'd say we're still waiting for a really wonderful field guide.
