Review title: One of the most thorough field guides on dragonflies
Product review: This work on dragonflies (damselflies not included) used to be the only complete field guide on dragonflies for the US at a user-friendly level. Other guides have now been published with more info, but this one is still a winner and first-rate for its size. Its only drawback is the small photos and lack clarity on many make it not as useful in the field.
