Eggs and Grurs of the House-Flv. 



The female house-fly lays about six hundred eggs in several batches on moist refuse. The grubs or maggots are long and slender, tapering 

 to the mouth. They feed upon the liquid portion of the refuse, and in a week are full grown. In another week they have passed through 

 the chrysalis stage and are winged Insects.
