While volume 1 includes several introductory chapters and treats 42 families of flies in the Lower Diptera, volume 2 covers the remaining 64 families of flies that make up the Higher Diptera (or Cyclorrhapha). These include families of house flies, fruit flies, bot flies, flower flies and many other lesser-known groups. The text is accompanies by over 1660 line drawings and photographs.
Flies of Rhagoletis (Diptera: Tephritidae) are economically important fruit pests (infesting specialty fruit crops including apples, blueberries and cherries), which also serve as models for studying modes of speciation and coevolutionary relationships with their hymenopteran parasitoids. There are new species within the genus which have not been previously formally described. One of these species is within the tabellaria species group. I describe the morphology of Rhagoletis bushi Hulbert & Smith, its geographic distribution, host association, phylogenetic relationships, and identify an associated species of parasitoid wasp. The new species infests the fruit of buffaloberry (Shepherdia argentea) in the Northern Great Plains of North America. There is a suite of morphological characters, and a unique host plant association, that are diagnostic of R. bushi. Further evidence for the validity of R. bushi and its placement within the tabellaria species group comes from DNA sequence data from multiple genetic loci. The phylogenetic relationships among Rhagoletis species groups remain unresolved despite analyses based on morphology, allozymes, and mitochondrial DNA. Most Nearctic Rhagoletis belong to one of five species groups (pomonella, tabellaria, cingulata, suavis , and ribicola groups), with two unplaced species (R. fausta and R. juniperina), all of which appear to be part of a larger monophyletic group that also includes some Palearctic taxa. Regarding the overall phylogeny of the genus, my goals were to 1) resolve phylogenetic relationships using mitochondrial (COI) and nuclear (28S, CAD, period, AATS) DNA sequences, and 2) to identify the monophyletic group containing these Nearctic species. Using Bayesian analysis of a combined dataset with 4399 aligned nucleotides, I inferred a well-supported monophyletic group containing the five Nearctic Rhagoletis species groups, plus R. fausta, R. juniperina, and two Palearctic species: R. batava and R. flavigenualis. Within this larger monophyletic assemblage, the five Nearctic species groups together are monophyletic as are four of the five individual species groups (not ribicola). Palearctic and Neotropical Rhagoletis were resolved into well-supported clades of taxa often sharing closely related host plants. A well-resolved phylogeny of Rhagoletis is a valuable tool for future work addressing questions pertaining to how history, geography and ecology have shaped the phylogenetic patterns we observe in the genus. It is often claimed that systematic biology is fundamental to all other areas of biology. I critically evaluate the acceptance of this claim by entomologists critically as it relates to the field of entomology. I also critically describe the justification and valuations for systematic biology using the framework of Boltanski and Thevenot's realms of worth and the philosophical framework for justification using virtues, desserts and outcomes. In order to accomplish these purposes, I critically analyze and review relevant entomological literature and interview practitioners of entomology and insect systematic biology. I find justification for systematic biology overwhelming takes the form of appeals to utilitarianism (both internally and externally focused) and are most relevant in the Industrial World. Additionally, some justifications given also pertain to the Civic World and to virtue. Evaluation of justification in systematic biology is important, especially as our globe becomes increasingly ecologically and politically unstable.
This is the first comprehensive synopsis of the biodiversity of Diptera, which with more than 150.000 described species contain more than one tenth of all described animal species. The first part is a review of what is already known, with treatments of all the major biogeographical regions and important archipelagoes; the second part contains case studies on open-ended taxa, Diptera as ecological indicators, and how to estimate the still unknown proportion of our fauna; and the third part discusses the digital and molecular tools needed to document the fauna. The book has an emphasis on principles and analytical approaches as well as on practical ‘how-to’ information and is intended for academicians and other professionals but with a significant outreach to students.

Fruit flies (Diptera: Tephritidae) are among the most destructive agricultural pests in the world, eating their way through acres and acres of citrus and other fruits at an alarming rate and forcing food and agriculture agencies to spend millions of dollars in control and management measures. But until now, the study of fruit flies has been traditionally biased towards applied aspects (e.g., management, monitoring, and mass rearing)-understandable, given the tremendous economic impact of this species. This work is the first that comprehensively addresses the study of the phylogeny and the evolution of fruit fly behavior. An international group of highly renowned scientists review the current state of knowledge and include considerable new findings on various aspects of fruit fly behavior, phylogeny and related subjects. In the past, the topics of phylogeny and evolution of behavior were barely addressed, and when so, often superficially. Fruit Flies (Tephritidae): Phylogeny and Evolution of Behavior is a definitive treatment, covering all behaviors in a broad range of tephritids. This volume is divided into eight sections:
