The Chrysomelidae are one of the most biodiverse groups of animals and plants and number over 35,000 described species, with at least as many undescribed. These three books on the biology of Chrysomelidae focus on specific areas of study: evolution, genetics and phylogeny; ecological aspects; general biological studies with descriptions of immature stages, as well as reproduction and embryology. Many of the chapters are contributed by experts in their particular field, especially from the New World, Europe and Asia. Although a plethora of information has been published on the subject, there are still gaps in our knowledge, but some of these are filled in these books by chapters on such ubjects as chrysomeloid pupae, elyron to body meshing mechanisms, insecticide resistance in the Colorado potato beetle, insect predators of chrysomelids, rickettsia-like organisms, mollicutes, fungal pathogens, weed biocontrol, radiation effects, embryonic development, parthenogenesis and the biology of Donaciinae, Palophaginae, Synetinae, Megalopodinae, and Eumolpinae.
