Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Syrphidae of Maine: Second Report The species discussed below are all aphidophagous, depend ing for growth and development on aphids, which are ravenous ly devoured during the larval stage of the fly. They must there fore be recognized as beneficial insects and their presence in any locality must be looked upon as an agricultural asset of no mean importance. To illustrate, - in an experiment with one of the species described below (see page 156) the writer found that, in five hours less than two days, three larvae had devoured a total Of 325 plant-lice, or an average Of not less than 54 a day for each larva. There is no reason to believe that this record is in any way exceptional. In fact in this case the thoroughness with which the aphids were devoured indicated a still greater capacity of the larvae. SO far as I am aware no previous record has been made of the metamorphoses Of these species. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2017-10-27 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Classification of the Larvae and Puparia of the Syrphidae of Illinois, Exclusive of Aquatic Forms The trend in recent years towards recognition of the necessity and value 'of studies in the immature taxonomy of insects has produced a number of useful papers on the classification of immature insects. How ever, there remains much to be done. During the course of a year's study of immature insects with Dr. William P. Hayes at the University of Illinois, the author was impressed with the need for more compact and comprehensive studies in many orders and the need for pioneer work in other orders where keys, if they exist at all, apply only to relatively small groups of families or. Genera. In the Diptera, whose larvae are perhaps the most varied in form and habit of those of any order, the classification of immature Orthorrhapha by Malloch provides the student of the order with an excellent working tool. In the Cyclorrhapha, however, the student has no aid in many groups at all; the larvae are little known, or described in widely scattered papers.
