THE GREEN LACEWING. 



Chrysopa calif or nica Coq. 

 (Fig. 51.) 



The adult insects are commonly known as. green lacewings, because 

 of their four delicate green lace-like wings. The color is light green, 

 the body having a conspicuous yellow longitudinal stripe down the 

 entire length of the dorsum. The adults measure about one inch in 

 length. The eggs are elongated, pearly white and attached to a long 

 thin stalk which suspends them about one fourth of an inch in the air. 

 The young vary from one eighth of an inch to three fourths of an inch 

 in length, and are yellow with reddish markings. They have very 

 formidable, long, sickle-like jaws or mandibles, which they insert into

the bodies of the host and by means of which the body juices are 

 extracted. The cocoons of the pups are small, pearly white, globular 

 bodies, held by threads, or a stiff white web, and are usually found 

 in the cracks or under the scales of bark or in any protected places. All 

 forms of the insect are abundant in the orchard. The eggs may be 

 observed attached to the leaves, while the young are usually found 

 feeding wherever soft-bodied insects occur. The adults are active on the 

 wdng and fly as soon as the branches of the tree are disturbed. 



THE BROWN LACEWING. 



Symphcrohiiiti aiKjustus Banks. 

 (Figs. 52-53.) 



The adults of the brown lacewing are slightly smaller than those of 

 the green lacewing and the wings are wider and the body more robust 

 in proportion to the size. The general color is brown, the wings being 

 artistically clouded with brown, as shown in the illustration (Fig. 52). 

 The eggs have never been observed but they hatch into small slate or 

 tan colored larvas which are exceedingly active. When full grown they 

 are nearly one half an inch long. The jaws or mandibles are not nearly
