ance. From the upi)or surface, the mine has a spotted 

 appearance due to the caterpillars not mining out the whole 

 interior, but eating a little here and there in the mine. The 

 mines are finished in September, the caterpillars transform 

 to pupae therein, and the winter is passed in this stage on the 

 fallen leaves. The minute Tineid moths which emerge in the 

 spring have golden brown front wings marked with white 

 streaks and spots and a black apical spot (Fig. 76). This 

 European miner is quite common on apple leaves in the 

 eastern United States, l)ut has not yet been recorded as 

 doing serious injury.
