Book Description
An international group of ecologists, entomologists and foresters have united to explore the life history traits of the Symphyta, or sawflies. This volume provides a treatment of these pests, their life history characteristics and evolutionary innovations for living on woody plants.

Book Description
Insect Clocks is mainly concerned with the phenomena in which ""environmental time"" has a practical implication for the life of insects for them to perform behavioral or physiological episodes at the ""right time"" and season. This text first discusses the concept of rhythms and clocks, along with the seasonal changes in the environment that affect a particular group of organisms. This book then explains circadian rhythms of insects. Photoperiodism and seasonal cycles of development; photoperiodic response, clock, and counter; and other types of insect clock are also tackled. This text concludes by explaining the anatomical location of photoreceptors and clocks. This publication will be invaluable to those interested in studying insects and their development affected by circles of influences.

Book Description
This volume is an outgrowth of a Symposium entitled "Evolution of Escape in Space and Time" held at the XV International Congress of Entomology in Washington, D. C., USA in August, 1976. The choice of topic was prompted by recent advances in evolutionary ecology and the apparent suitability of insect migration and dia pause as appropriate material for evolutionary studies. In the event, that choice seems amply justified as I hope a perusal of these papers will show. These Sympos ium papers hardly cover the topic of the evolution of escape mechanisms exhaustively, and I am sure everyone will have his favorite lacuna. Some of the more obvious ones are indicated by Professor Southwood in his Concluding Remarks at the end of the book. The purpose of the Symposium, however, was not complete coverage, but rather to indicate the potential inherent in insect migration and diapause for the study of evolutionary problems. In that I think we have succeeded reasonably well. These papers are expanded and in some cases somewhat altered versions of the papers delivered in Washington. This has allowed greater coverage of the topics in question. I suggested a format of a general overview of a topic emphasizing the author's own research con tributions. In general the papers follow this outline although emphases vary. Two of the authors, Dr. Rainey and Dr. Lumme, were unable to attend the Symposium. Dr. Rainey's paper was read by Mr. Frank Walsh, but Dr.
