a half-grown condition, so that these insects may hibernate 



in two stages of their life. 



The Tree Crickets are generally greenish or whitish 



insects, living on the leaves and branches of trees, shrubs, 

 and herbs. They feed upon plant lice or . 

 aphides, and thus differ in their food 

 habits from most of the order. But they 

 often do considerable damage to rasp- 

 berry canes by depositing their eggs in 

 long rows in the pith. Such canes are 

 likely to split open and winter-kill. 



The Mole Crickets are among the most 

 remarkable examples of insect life. They 

 are perfectly adapted to an underground, 

 burrowing life. The front legs are de- 

 veloped into digging organs by means 

 of which the insect can make a tunnel 

 in the soil, through which the cylindri- 

 cal body easily passes. They are brown 

 in color, and their food consists of under- 

 MoLE Cricket ground roots of various sorts. 



Cockroaches and Walking Sticks 



The Cockroaches (Blattidae) are characterized by their 

 flattened forms, their legs fitted for running, their flat over- 

 lapping front wings, and their long, bristlelike, many-jointed 

 antennae. Many forms of Cockroaches are wingless, though 

 the typical full-grown form has well-developed wings. 

 These insects feed upon almost anything, being commonly 

 found about kitchens and sheds, especially where there are 

 water pipes. Some species are also found in the woods, 

 undfer the bark of trees, where they feed upon a variety of 

 materials. Probably the original home of all the species
