 it begins to move, and may then be seen hovering 

 about the little apples, which, by the time the 

 moth leaves the chrysalis, the middle of June, 

 are well knit, and consequently fit for the reception 

 of its eggs, which it lays in the eyes, one only 

 in each, by introducing its long ovipositor between
