Available in PDF, EPUB and Kindle. Book excerpt: Larvae of Syrphinae and of the tribe Pipizini (of doubtful position but here referred to the Eristalinae) are probably all predators of Homoptera (particularly aphids) and of a few other groups of insects. [...] In males of all Nearctic Syrphinae the eyes meet on the frons or are separated by at most the width of two ommatidia, and the apex of the abdomen is asymmetrical with the genital capsule usually conspicuous in ventral view. [...] In females the eyes are widely separated on the frons and the apex of the abdomen is symmetricaL Du"sek and L6ska (I974b), after observing that early spring adult specimens of some species were much darker than summer specimens, showed that temperature during pupation in two species of Eupeodes (as Metasyrphus), in one of Episyrphus Matsumura, and in one of Sphaerophoria had a very marked effect o [...] Second, larvae of most or all species of Syrphinae and of species of the tribe Pipizini (Eristalinae or Syrphinae) are predators of various groups of Homoptera (particularly Aphidoidea), of eggs and larvae of Chrysomelidae, and, outside Canada, ofThysanoptera nymphs and oflarvae ofTortricidae. [...] Some species of Eumerus Meigen and Merodon Meigen in bulbs of ornamental Liliaceae or of onions and one or more species of Cheilosia Meigen in burrows of Scolytidae in timber cause disfiguration of the wood known as black check.
Download or read book Field Guide to the Flower Flies of Northeastern North America written by Jeffrey H. Skevington and published by Princeton University Press. This book was released on 2019-05-14 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: A groundbreaking guide to flower flies in North America This is the first comprehensive field guide to the flower flies (also known as hover flies) of northeastern North America. Flower flies are, along with bees, our most important pollinators. Found in a varied range of habitats, from backyard gardens to aquatic ecosystems, these flies are often overlooked because many of their species mimic bees or wasps. Despite this, many species are distinctive and even subtly differentiated species can be accurately identified. This handy and informative guide teaches you how. With more than 3,000 color photographs and 400 maps, this guide covers all 416 species of flower flies that occur north of Tennessee and east of the Dakotas, including the high Arctic and Greenland. Each species account provides information on size, identification, abundance, and flight time, along with notes on behavior, classification, hybridization, habitats, larvae, and more. Summarizing the current scientific understanding of our flower fly fauna, this is an indispensable resource for anyone, amateur naturalist or scientist, interested in discovering the beauty of these insects. · 3000+ color photos (field and museum shots) · Multiple images per species, with arrows highlighting key field marks · Grayscale images showing the actual size of the insect · Range maps for each species · Information on size, identification features, abundance, flight times, and more

This book was released on 2012-12-02 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing environmental hazard and human impact on different ecosystems, with special emphasis on rural landscapes is the main topic of different environmental policies designed in developed countries and needed in most developing countries. This book covers the bioindication approach of rural landscapes and man managed ecosystems including both urbanised and industrialised ones. The main techniques and taxa used for bioindication are considered in detail. Remediation and contamination is faced with diversity, abundance and dominance of biota, mostly invertebrates. Invertebrate Biodiversity as Bioindicators of Sustainable Landscapes provides a basic tool for students and scientists involved in landscape ecology and planning, environmental sciences, landscape remediation and pollution.
