368 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



turbed, that they may usually be picked off and crushed, and so 

 rarely become sufficiently numerous to warrant other treatment. 

 They may be readily controlled by spraying or dusting with 

 arsenicals. 



The Celery Looper * 



This species is very closely related to the cabbage looper 

 and occurs throughout the Northern States east of the Rocky 

 Mountains. According to Forbes and Hart it is more common 

 than the cabbage looper in Illinois, where it is a serious pest of 

 celery and has been reared on sugar-beet, but elsewhere it is 

 not as common. 



The moth has a wing expanse of about two inches, the fore- 

 wings being purplish brown with darker shades of velvety brown

and with a prominent silvery white discal spot, while the hind- 

 wings are yellowish, strongly banded with dark fuscous. The 

 caterpillar or larva is similar to that of the cabbage looper, but 

 the spiracles are surrounded with black rings, while in the 

 cabbage looper these rings are indistinct or wanting. 



Forbes and Hart believe that there are three broods in a 

 year. "The caterpillars of the first generation of the year hatch 

 late in May and get their growth late in June or early in July. 

 The life of the second generation extends from the first part 

 of July to the middle of September, and the third begins to issue 

 from the egg early in October. This brood hibernates about 

 half grown, attaining full size during the latter part of April." 



Control. No accounts of experiments in control are on record, 

 but doubtless the same measures as used against the cabbage 

 looper will be found applicable.
