THE CODLIN MOTH. 49 



three weeks in a closely-stoppered bottle, without apparent 

 injury to the grub. In January and February the larva 

 spins a silky cocoon prior to changing into the chrysalid 

 stage, having previously fastened around itself a transparent 

 silky covering (see Plate II., Fig. 5), which can easily be 

 seen by any one examining either the crevices in the bark 

 or the bandages. 



When the moth first emerges from the chrysalis it is of 

 a beautiful colour, and on the hinder position of the fore- 

 wings are two bronzy patches, with a golden margin or 

 band to each, these particular tints being very difficult to 

 show on a plate. The hind wings are of a light golden- 

 brown, and the moth itself measures about half-an-inch 

 across the wings when fully expanded.* For convenience 

 sake the measurements are mostly given according to the 

 French system of lines, and the accompanying engraving 

 will explain the method of using this system, which has 

 been also adopted by Mathew Cooke

Specimens of the " Codlin," as well as other moths and 

 butterflies, are always better and more perfect, both in 

 shape and colour, if reared from the bandages obtained 

 from the trees, or from the fruit itself, as if caught on the 

 wing, the specimens are mostly rubbed or otherwise injured, 

 and it has been observed that no sooner do the perfect 

 insects emerge from the chrysalis than they very soon 

 become lively, and pairing takes place within a few hours, 

 the eggs being deposited shortly after, and thus if the 

 specimens are not captured at once, they become next to 

 useless for either comparison or for the cabinet. 



Mr. W. Kershaw, one of our best observers, tells me 

 that he has captured the moth in the middle of the day, 

 but I have not seen this fact for myself, although I have 

 no doubt whatever but that his statement is correct. 



* The measurements of insects in this Handbook are given in inches and lines. 

 The above cut represents one inch divided into lines and fractions thereof.
