ENCYCLODEPIA OF SOUTH AMERICAN AQUATIC INSECTS - ODONATA-ZYGOPTERA

Zygoptera completes the two volume work on the order Odonata in the Encyclopedia of South American Aquatic Insects. The Zygoptera volume encompasses the relatively small dragonflies, often called damselflies. A brief review of the biology of the group includes illustrations of the main morphological features as well as explanations of alternative systems for naming the wing veins and other characteristics commonly used to distinguish the species. This will show the user of the identification keys in the volume the alternative names for the anatomical structures most frequently encountered in the literature. The sections on the morphology of the adults and larvae are followed by brief discussions of ecological and zoogeographical factors influencing the distribution of the dragonflies and instructions on the various methods used to observe, collect, preserve, and examine specimens.
