14 GRAMMAR OF ENTOMOLOGY. 



39. Towards evening, in fact, just at sunset, 

 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 

 the leaves of the calyx, which form a tent above 

 it that effectually shields it from the inclemency 

 of the weather, or any other casualty. 



40. As soon as the egg hatches, the little grub 

 gnaws a hole in the crown of the apple, and soon 

 buries itsel/ in its substance ; and it is worthy of 

 remark that the rind of the apple, as if to afford 

 every facility to the destroyer, is thinner here than 

 in any other part, and consequently more easily 

 pierced : the apple most commonly attacked is 

 the codling, a large early sort, which ripens in 

 July and August. 



41. The grub, controlled by an unvarying 

 instinct, eats into the apple obliquely downwards, 

 and by thus avoiding the core and pips in no way 

 hinders its growth : at first it makes but slow

 after a fortnight its size and its operations have 

 much increased ; it has now eaten half way down 

 the apple, and the position of the hole at the top, 

 if the apple continue upright, or nearly so, is
