when extended, three-tenths of an inch, being of about the same 

 proportions as the larva of the common species, but is readily 

 separable by its ochraceous orange color. 



Remedies are those indicated for the common asparagus 

 beetle, with the exception of caustic lime and other measures 

 that are directed solely against that species, but the habit of 

 the larva of living within the berry places it for that period 

 beyond the reach of insecticides. 



The Asparagus Miner {Agromyza simplex Loew.). — Aspara- 

 gus stalks are sometimes considerably injured by a maggot 

 (fig. 55jir, a) which mines undei the skin near or just beneath 

 the base. The appearance of the affected stalk (/) is charac- 

 teristic. The parent insect is a small black fly. 



Remedial Suggestions. — Permit a few volunteer asparagus
