The Long-Horned Grasshoppers 



in a bunch. Each female lays from 100 to 150 eggs. In the 

 spring the egg splits along its top edge and the young katydid, 

 very pale in color, emerges. In Missouri the skin is cast five 

 times and the perfect insect appears from July to August, the 

 songs being most commonly heard in the latter month. Mr. 

 Scudder, who has studied the notes of crickets and grasshoppers 

 from the musical standpoint, states that the day song of the katy- 

 did differs from the night song. In its northern range the insect 

 is single brooded but in the far southern States there are two 

 generations annually. The eggs of the angular-winged katydid 

 are stung by the curious chalcidid parasite known as Eupelmus 

 mirabilis Walsh, called by its describer the "back-rolling 

 wonder" from the fact that the abdomen is frequently turned 

 backwards and upwards until it nearly reaches the head, the hind 

 legs being turned in the same direction so that the insect almost 

 forms a ball. 



This parasite, male and female, appears at the bottom of 

 Fig. 226.
