At any time of the year, and in almost any small pool of stagnant water, the familiar "wrig- glers," which are the larvae or first young stage, of the mosquito, can be found. "A ditch in a wood choked with fallen leaves is one of the best hunting ; Some of the ''^•^•mJsquiols^"^"' material from which the following notes were made came from a watering trough in a pasture, and some of it came from a barrel of water containing considerable decaying matter. In many localities it is necessary only to ex- pose an open pail or cask of water for a few days in order to get a thriving colony of mosquitoes. The mosquito larvae (wrigglers) are so distinctive in structure and manner that no trouble will be had thru mistaking other aquatic insect larva or other aquatic animals for them. By reference to the figure of the larva (fig. 5) this characteris- tic appearance can be got acquainted with; in addition, the characteristic wriggling of the body when the creature is mov- ing thru the water, and the hanging head downward from the sur- face when at rest, are manners which make the mosquito larvae readily recognizable. Besides the larvae, there may be found both the eggs and the pupae (second young stage). The eggs are in small masses which float on the surface of the water, resembling at careless glance nothing else so much as a largish bit of soot. These little, float- ing, sooty bits are composed of a single layer of slender, elongate eggs standing on end, and loosely fastened together to form a nar- row, irregular, little raft, slightly concave on the upper surface. The pupa (fig. 6) is composed of a big bulbous head and a. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - colorati
