Favorite Flies and Their Histories (Paperback)


Purchase of this book includes free trial access to www.million-books.com where you can read more than a million books for free. This is an OCR edition with typos. Excerpt from book: to their many peculiarities, they do not rightly belong to any of the older established orders, but must be noted as distinct in specialization, and are difficult to locate. They are named by some writers the Plectoptera, but this is so similar in orthography to Plecoptera that, to avoid confusion, the latest authorities place them in the second order, Ephemeroptera. As Day-flies, or Drakes, they exist for a brief time in two distinct stages, the sub-imago (called by Theakston the pseudo-imago) and the imago; in these forms they possess only the most rudimentary mouth-parts, and take no food. The thorax is peculiar in being globular; the prothorax, mesotho- rax, and metathorax are each very small. The abdomen is very long and slender, terminating in two or three long delicate stylets. The wings are net-veined. The mature insects exist but a short time, and for the purpose of reproduction only; but as larvae and pupae they live one, two, or three years, burrowing in the mud, hiding under stones- and among grass and weeds. During this time they pass through many changes and a gradual development until the tune arrives for them to assume the imago. In different localities they are known under various names, as May-flies, or day-flies, but generally drakes, because of the peculiar reversed and elevated position of the stylets; owing to this they are also known as cocktails, and in Ireland as caughlans, meaning cocktails. After leaving the pupa - skins, they may be seen assembled in groups or swarms about the waters on summer evenings. In some places they appear in immense numbers, so that they seem to fall in showers. By many persons they are thought to emerge from the caddis cases; but this is an error, the larva being hatched from the egg laid by the parent drake or c...
