Notes on the Biology of the Muscid Fly, Pyrellia Serena Meigen, with Special Reference to its Hibernation

During the course of some field studies on hibernation in the Chicago region,[*][1] interest was aroused in the muscid fly, Pyrellia serena Meigen,[†][2] because of its frequent occurrence in the field and because of its massed method of hibernation. It was thought that this species could possibly be reared in the laboratory and used as experimental material, but unfortunately its life history was unknown. A number of observations were made on its hibernation, and an attempt was made to learn something of the rest of its life history and habits. Although this project was not completed, some data were obtained which seem to be worth recording. These data were obtained chiefly by field observation, but a few experiments were also performed in the laboratory. [1]: #fn-1 [2]: #fn-2
