 Katydid. 



Grass green, face, under surface 

 and first and second legs yellowish 

 green. Length of body 25-30 mm. 



The Katydids and meadow grasshop- 

 pers belong here. They are usually 

 green and the female has a sword-llke ovipositor. The camel 

 crickets, queerly shaped, humpbacked wingless forms that live In 

 dark places, are also Included In the family. They range from a 

 mottled light brown to dark brown In color. 



3a Antennae short 4 



3b Antennae long and slender. Ovipositor usually long and 

 nearly cylindrical. (The Crickets) (in part) Fig. 74. 



Family 7, GRYLLIDAE 



Fig. 74. Pecan thus nlveus De G, The Snowy 

 Tree Cricket. 



Pale green or white. First segment of 

 antennae with a round black dot. This and 

 other tree crickets are persistent singers. 

 Their high pitched trills which continue 

 throughout the night are made with the 

 wings. Only the males sing. Length of 

 body, 12-15 mm. (After Fulton) 



There are a number of subfamilies of 

 crickets differing In structure and habits. 

 The sword bearing crickets, bush crickets, 

 tree crickets, field crickets and tiny

They are all lar^elv vegetable feeders. The 

 family Is an important one. 

 4a Front legs widened, fitted for burrowing. (The Mole 

 Crickets) (in part^ Fig. 75 Family i, GRYLLIDAE 



Fig. 75. Gryllotalpa hexadactyla Party. 

 The Common Mole Cricket. 



Reddish brown, thickly covered with short 

 fine hairs; claws, and veins of wings 

 darker. Wings quite variable in length. 

 Length of body 20-30 mm. 



The mole crickets, though not often seen, 

 never fail to attract attention when found. 

 They burrow in mud at the sides of ponds 

 and streams and are nocturnal in habits. 

 Some persistent searching in favorable 

 places should result in securing some speci- 

 mens of this highly interesting Insect for 

 one's collection. They cause injury by 

 feeding on the roots of plants.
