Larvae of Eulia pinatubana live in tubes made by fasten- 

 ing together the needles of white pine and then feed on 

 the outer ends. 



We now come to a series of families which contain 

 "really righty" mzcro-lepidoptera, but, as Smith said, 

 "many of them are veritable gems of beauty, far exceeding 

 in brilliancy and richness their relatives of larger size." 

 The larvae are largely miners in leaves. 



"And there's never a blade nor leaf too mean 

 To be some happy creature's palace." 



YPONOMEUTID^: 



Larvae of Plutella maculipennis are common on cabbage 

 and other crucifers; the pupae can be easily seen through 

 the delicate, lacy cocoons on the cabbage stalks. 



Larvae of Argyresthia thuiella mine arbor- vitae leaves. 



GELECHIIDyE 



The Angoumois Grain-moth is another 



itotroga pestiferous importation from Europe and 



cerealella . . 



receives its name from the fact that in 



1760 it was found to swarm in all the wheat-fields and 

 granaries of Angoumois and of the neighboring provinces 

 [of France], the afflicted inhabitants being deprived of their 

 principal staple, and threatened with famine and pestilence 

 from want of wholesome bread." It apparently landed in 

 North Carolina about 1/30. The larvae feed within the 

 seeds of wheat, corn, oats, rye, barley, sorghum, and cow- 

 peas, eating to, but not through, the surface. The creature 

 hibernates as a larva wrapped in silk, and pupates in 

 the spring. The adult, which resembles the ordinary 

 clothes-moth, emerges in May or June and oviposits on 

 the young grain-heads. There are two or three generations 

 a year. 



Larvae of Metzneria lapella feed on seeds of burdock, 

 hibernating in the burs.
