After resting for a short time on the old pupal skin and allowing the wings and body to ex- pand and harden, the adult mosquito flies away. In a few days the females are ready to lay eggs. From the time breeding starts in the spring until the cold weather of fall drives the adult females into hibernation, brood succeeds brood. The type of rainy weather which will keep rainwater-holding places continually full without causing them to .overflow and wash the larvae away is the weather most favorable to this species, for with heavy precipitation, no sooner does a brood get started than it is washed away. Extreme dry weather is likewise unfavorable,.
