Book Description

Excerpt from Transactions of the American Entomological Society, Vol. 45 This paper is the result of about two years interrupted study of the dipterous family Cyrtidae. It is an interesting little group of insects with a remarkable range of variation in structure. The collecting of more material will no doubt cause some changes to be made in the status of a few species, and further study will reveal other characters for the separation of the different forms. The species of Cyrtidae are very rare, at least until their local haunts are known. In several places along the Pacific Coast large series of Eulonchus have been collected, but these are rarely found in any great numbers. The family is a small one and some species are known from only one or two specimens. Few collectors have any large number of these flies, and even those who have made a search for them have found them only at rare intervals. The species are not economically important, those in which the early stages are known being parasitic in the egg cases or in the bodies of spiders. In only a few species have the early stages been found and we know nothing of the life histories of some genera.
