The Adults. — The adults of both Bud Worms are moths or "candle 

 flies." They differ very remarkably from each other. The adult of 

 the True Bud Worm (Fig. 25) is a beautiful moth with a wing ex-

pause of an inch and a half. The four wings are light green in 

 color, crossed by three bands of lighter color, the lighter bands being 

 bordered on the outer edges with dusky. The hind wings are 



whitish with darker veins and 

 dusky outer border, which is 

 very heavy in the male, but not 

 so prominent in the female. 



The adults of the False Bud 

 Worm (Figs. 23a and 26) 

 vary in color almost as much 

 as the larvae. Their color 

 ranges from a reddish brown, 

 which is almost coppery and 

 heavily marked with darker, to 

 a lighter olive-yellow, scarcely 

 marked at all. 



Life-history of the True Bud Worm. — Based upon field observations 

 mainly of the presence of the Bud Worms in tobacco, the life-history 

 of the True Bud Worm is about as follows : Moths issue from over- 

 wintering pupa? in the spring. Nearly full-grown larvae are found 

 in the bnds of tobacco as early as the middle of June and as late as 

 early July. These pupate in little cells in the ground. Moths from 

 these pupae evidently emerge all through August. The larvae of the 

 second generation are found in the tobacco field from late August to 

 late September. The larvae of the first generation feed on the un- 

 folding buds of tobacco and the larvae of the second generation feed
