428 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



eral appearance as that of the preceding species, but may be dis- 

 tinguished by its orange color. The eggs are laid singly, and are 

 attached on the sides instead of on end. They are deposited 

 mostly on old plants toward the ends of the shoots which bear 

 ripening berries lower down. Soon after a larva hatches it finds its 

 way to a berry and feeds upon its ripening pulp, from which it 

 migrates to another, feeding upon several, perhaps, before full 

 growth is obtained, when it drops to the ground and pupates like 

 the last species. The life cycle is essentially the same and there 

 are probably the same number of generations. 



Control. The remedies advocated for the previous species 

 will be found satisfactory except those which an; directed against 

 the larvae, as the habit of the larva of concealing itself in the berry 

 would make the application of insecticides to the secdstalks of 

 little use. 



The Asparagus Miner * 



Occasionally injury by the small white maggots of a fly have 

 been observed in the asparagus beds of Long Island, California, 

 Pennsylvania, Massachusetts and District of Columbia, but the 

 damage seems rarely to be very serious. The adult is a small black 

 fly about one-sixth of an inch long and is usually found on the 

 flowers of the asparagus, and occurs from New England to Ten- 

 nessee. These flies emerge early in June. The exact manner of 

 egg-laying has not been observed, but the young maggots are found 

 mining just beneath the surface of the stalks, especially young 

 stalks. The maggots are about one-fifth an inch long, pure 

 white, except the black rasping hooks which project from the head. 

 When full grown the maggots change to puparia beneath the epi- 

 dermis. The next brood of adult flies emerge early in August. 

 A second brood of maggots seems to occur and the puparia of the 

 second brood pass the winter, and from them come the flies early 

 the next summer.
