. The anatomy, physiology, morphology and development of the blow-fly (Calliphora erythrocephala.) A study in the comparative anatomy and morphology of insects; with plates and illustrations executed directly from the drawings of the author;. Blowflies. 6 THE LIFE-HISTORY OF THE BLOW-FLY. our dwellings until late in autumn, although they abound in butchers' shops, slaughter-houses, and similar places. The question of hibernation is a difficult one to settle. All ' winter flies' are, I believe, immature, as I have never found one with ripe eggs ; still, I strongly suspect mature females hibernate occasionally. In the winter of 1889 I had a bell-glass in my laboratory full of immature blow-flies, which had recently issued from the pupae. One very cold morning when I went in not a fly was to be seen. I imagined the bell-glass had been lifted, and that my flies had escaped. On closer investigation, however, I discovered them all closely huddled together in a hollow under the base of a cup containing pupte. The cup had been slightly tilted, and every insect had retreated into this narrow space. As soon as the temperature of the room rose to 55° Fahr., the insects emerged from their concealment, and were as lively as TUB FLESH-FLY. I^Sareophaga caniaria.).
