Mixed feelings about this handbook. It gives an excellent introduction to an enormous subject, and provides a manageable overview using Linnaean taxonomy (family tree), within its 250 pages. Its illustrations are clear and detailed and in glorious colour. Many of the bugs are absolutely beautiful.
However, it recognises its own limitations by saying "... impossible to include [all 1500 families of terrestrial arthropods] in this book. We have chosen a broad range from around the world, including [those that] are particularly important, common or simply fascinating in some way".
As a result, if you really need something to identify the creatures in the area where you live, then this handbook won't get you very far. For example, the entire world's Lepidoptera (butterflies and moths) are dealt with in 20 pages and the Odonata (dragonflies and damselflies) in only 5. Compare this with, say, the 84 and 21 pages respectively (out of a total of 320) in Bob Gibbons' "Field Guide to Insects of Britain and Northern Europe", which I found to be of much more practical use, simply because its scope is geographically far less ambitious. The Gibbons book won't help US readers, I know, but the comparison is likely to be true for any good quality LOCAL field guide.
The DK/Smithsonian production is attractive and eye-catching, and could very well spark a youngster's interest in the subject, but it is probably more suited to the coffee table than to the field and the garden.
