INJURIOUS AND BENEFICIAL INSECTS OF CALIFORNIA. 



Food Plants. — The larvae work upon the roots of various plants, 

 including blackberries, loganberries, raspberries, roses, strawberries 

 and probably many unrecorded hosts. The adults have been found 

 feeding upon Abutilon, Acacia, Achyrantes, apricot, azalea, Begonia, 

 California fan palm (Washingtonia flifera) and other palms, camellia,

 unable to fly, it is only necessary to employ some means to keep them 

 from crawling up the trunks or branches of the trees or plants. On 

 low trailing plants this is very difficult, but on trees the use of tangle- 

 foot or cotton bands about two feet from the ground has proven very
