This book recounts the habits of interesting and unusual exceptions to the rule that insects are typically terrestrial forms of life. It examines different ways that groups of species developed modes of existence in or on the surface of water, and gives reasons why the gross morphology of insects is not favorable for life in or near bodies of wa

This order once encompassed all insects with a complex network of wing veins, regardless of whether their metamorphosis was incomplete or complete.  By the early 20th century, most of the species had been transferred to new orders, leaving only a small percentage of the insects once assigned to the Neuroptera remaining in that order.  By the second half of the 20th century, some of the taxonomists began to believe that the fragmentation of thi...

This work was begun to provide keys to the aquatic insect species known from Brazil. The original goal was to include all genera known from South America and all species from Brazil, but for most groups, the scope was expanded to encompass all species in South America, and, in some cases, to include terrestrial species of orders comprising both terrestrial and aquatic taxa. In no case is a taxonomic rev1s10n of any group undertaken, although r...

Superbly written, this is an account by a participant in the airlift that supplied the blockaded capital of the Khmer Republic and several provincial capitals with food and other necessities of life during the last year of the United States' direct involvement in the Indochina War.

This beautiful volume, with hundreds of fascinating hand-drawn illustrations, completes the two-volume work on the order Odonata in the Encyclopedia of South American Aquatic Insects. The Zygoptera volume encompasses the small dragonflies often called damselflies. The sections on the morphology of the adults and larvae are followed by discussions of factors influencing their distribution and instructions on the methods used to observe, collect...

There are many famous wetlands in the world that have been deemed important for the homeostasis ofthe biosphere and accorded some form ofprotected status in view of the richness of their flora and fauna. T}1e Pantanal, located almost directly in the center ofthe South American continent, is among the largest such wetlands in the world. It is, in fact, the largest wetland that is still in a nearly natural state and has not been extensively modi...

Hemiptera - Heteroptera encompasses the three well-defined suborders of the true bugs which are adapted to an aquatic or littoral habitat.  The book begins with a section on the biology these insects and provides illustrations of the basic features of their morphology and outlines the larval development.  Brief outlines of the ecological and zoogeographical peculiarities of the three aquatic suborders are presented individually, and various me...

Anisoptera, the first of two volumes on the Odonata, encompasses the large dragonfly species. To help readers understand naming conventions, a brief introductory biological review of the group includes illustrations of the main morphological features as well as explanations of alternative systems for naming the wing veins and other structures. The text introduces keys to facilitate identification of adult dragonflies and the known larvae. Beyo...

Research was carried out in Udorn Thani beginning in September, 1975, in order to elucidate the effects of seasonal changes on the aquatic community of a rice field. Physical and chemical changes that occur during the course of a year were recorded and related to the structure and activity of the aquatic biological com­ munity. A rice field was selected that is typical of the countless habitats of this kind that are found in Northeastern Thail...
