Turk" when they leave the fruit to enter the ground for pupation. 

 Other insects actually eat into the fruit as it lies upon the ground, 

 to seize the larvae, drag them out, and eat them. Some of the 

 ground-beetles mentioned before are of great assistance to the 

 fruit-growers, and the Harpalus pennsylvanicus De G., illustrated 

 in Fig. 22, is of special importance, as it is very common in our 

 orchards. It's larva is illustrated in Fig. 216, in the act of de- 

 vouring a curculio larva. Other 'members of this useful family 

 of insects are also good friends, and should be known as such.

Fig. 217 shows the larva and adult of one of our most com- 

 mon soldier-beetles, Chauliognathus americanus Forst. The 

 beetles themselves occur in large numbers on the flowers of the 

 golden-rod; they are yellowish with black markings, as shown in 

 the illustration. Their larva? frequently work their way into the 

 plum in search of their prey and do this even while the fruit is 

 still on the tree.
