Excerpt from American Black Flies, or Buffalo Gnats It is not considered necessary to rewrite the history of the Simuliidae in this paper, but a bibliography is given on page 69 of the principal papers on the American species in the group, which may be consulted with reference to the biology of the species.

Excerpt from Mosquitoes, Gnats, Craneflies, Midges and Flies of the Northern StatesThe mosquitos, gnats, flies, ticks, and fleas constitute the order Dz'ptera of the class Insecta. They have only two wings (a few Wingless excepted) in place of hind Wings, they have a minute hair with a knob on the end of each called the balancers; mostly covered by a scale when at rest. Their mouth parts are formed for sucking or lapping, never for biting, though often enclosed in sharp horny needles for piercing; some have their tongues enclosed in a soft trunk. Their food is always liquid. They lay their eggs inthe water, on fruit or on various growing or decaying vegetable or animal matter, on which their larvze, footless maggots live. The maggots when full grown transform to pupa, mostly enclosed in their own dried skin, though some times naked.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.
