INJURIOUS AND BENEFICIAL INSECTS OP CALIFORNIA. 



451 



Fig. 460. — Pupa cases of the California case-bearer. Coleophora sacramenta Hein- 

 rich, on prune leaves. Natural size. Specimens collected in Santa Clara Countv 

 by Leroy Childs. (Original) 



Life History. — This moth is a new 

 insect and other than a few field 

 observations, nothing is known of its 

 life history. Mr. Leroy Childs, who 

 discovered it, found the pupae quite 

 thick upon prune trees in Santa Clara 

 County, May 6, 1914. The work of 

 the larvas was also in evidence, but 

 had been done some time previous to 

 that time. There is usually only one 

 case to a leaf, but occasionally two, 

 three and even four or five may be 

 found. 



Nature of Work. — The larva? eat 

 ragged holes in the margins and 

 through the leaves, as shown in 

 Pig. 460. 



Distribution. — So far this species 

 has been taken only in Santa Clara 

 County, but inasmuch as it is a native 

 species it probably occurs elsewhere 

 along the middle coast region. 



Food Plant. — It has so far been 

 taken only upon the prune, but prob- 

 ably also works upon other fruit trees.
