INJURIOUS AND BENEFICIAL INSECTS OF CALIFORNIA. 21 



Fig. 19. — Lima beans showing- the work of the lima bean symphylid, 

 Scutigerella calif ornica (Woodw. ). Enlarged twice. (Original) 



Food Plants. — The tender shoots of asparagus and morning-glory 

 before they come to the surface of the ground and the germinating 

 seeds of lima beans and peas are 

 hosts. Mr. B. R. Ong also found 

 it attacking the fleshy roots of 

 wild mustard and radish. 



Control. — Inasmuch as but 

 comparatively few crops are in- 

 jured by this pest, a rotation of 

 crops may be a means of con- 

 trolling it. Bare fallow may 

 even be necessary to accomplish 

 the desired destruction of the 

 pest.
