fully grown, it creeps into some corner of the hive, or into 

 some other sheltered place, and spins a tough white cocoon 

 (Fig. 3686), intermingled with its own black excrements. 

 The perfect moth (Fig. 368, d and e,) has dusky gray fore-

CHAPTER CCLI. 



What are they, Friends or Enemies? 



At various times during the last two years, I have received 

 specimens of insects reported to be feeding upon fruits, and I 

 refer to some of them as follows : 



Fig. 369.— Larva of Lace-winged Fly — color, gray. Fig. 369. 



1st. Mr. Scott, residing near this city (Sacra- ^iuk 



mento), brought me some ripe peaches in which "-^^s^ 

 were small insects, eating in holes made through y^^^^ 

 the skin of the fruit. The holes were less than one ra 

 line in diameter, and from two to four lines in depth. ^ 



By removing the insects from the holes in the fruit, 

 I found that the supposed new pest was the larva of a Chrys- 

 opa (Fig. 869) or lace-winged fly. That they were feeding 

 ii]»oii tlic fruit is beyond question; Wut i)rol)ably the open- 

 ing liad been made by a species of plant-bug, or by the striped 

 cucumber beetle (D. cittata), which infested the trees. I could 

 not find any plant-lice on the trees, therefore the larva of the 

 Chrysopa may have entered the punctures made by some other 

 insect to feed upon the fruit. 



2d. I have also received specimens of a species of lady- 

 bird, said to attack cherries when ripe. It is the Cocci nella 

 ■')-n()t(ifa var. ('alifor)rira. (Fig. 370, Plate 4.)
