hopper to distinguish it from the common grasshopper or 

 locust. This resembles a cricket or a locust in general struct- 

 ure. It is found in grass and in the trees, hence its color for 

 the sake of protection is green. The Meadow Grasshopper 

 is a common kind. It is long and slender, with 

 wings that extend beyond its body. It has 

 very long antennae, and a pair of very long 

 jumping legs. This kind is seen m the tall 

 grass of meadows, clinging to the blades and 

 stalks. The male makes a chirping noise by

 wing of cricket. The Katydid is another kind of grasshopper, 



that lives in the trees, and in the quiet watches of the night 

 argues continuously, "Katy did," "Katy didn't." The 

 sound is made as by the other grasshoppers. The Katydid 

 looks somewhat like a cricket with long, broad wings. 



On hot summer days we often hear a shrill, trilling sound 

 emanating from the tall 

 trees, a sound that resem- 

 bles a miniature snare-drum 

 or a miniature alarm-clock 

 going off and gradually run- 

 ning down. This sound is 

 made by the Dog-day Har- 

 vest-fly or Two-year Cicada, 

 or perhaps by the Seventeen- 

 year Cicada. These insects 

 are sometimes, but erroneously, called the "Locust." The 

 cicada is related to the Bugs (Hemiptera). 



It is a rather large insect, nearly two inches in length, with 

 clear, strongly veined wings. It has a broad, triangular head,
