THE CODLING-MOTH.

spun beforehand. One ingenious entomologist contrived to force these insects to spin 

 their webs on paper, and thus obtained a quantity of silk, which he afterwards had 

 manufactured into different articles. 



The larvae of the Tortricidae frequently reside within leaves, and either roll them up 

 in the manner which has just been described, or get into the middle of a bud or cluster 

 of leaves, and draw them together with their silken nets. The leaves of the willow are 

 very liable to the attacks of these insects. A very pretty and well-known species of 

 these moths is the OAK-LEAF ROLLER (Tortrix viridana), a moth of a beautiful apple- 

 green upon the upper wings. In some places, these moths swarm to a fearful extent, 

 stripping whole trees of their leaves. I have known the oaks to be surrounded with 

 whole clouds of these moths, fluttering about like gnats, and forming an exhaustless 

 banquet to the empis-flies, which were catching them by thousands, embracing them 

 in their long legs, and flying about with their prey, sucking their juices like so many 

 winged vampires.

Other species live beneath the bark of trees, or even burrow into the wood, while 

 others are hatched in the interior of fruits, and live unsuspected in their retreats until 

 they are on the point of changing to their pupa form, when they eat their way out, and 

 leave a round hole as a memento of their presence. The CODLING-MOTH is one of the 

 commonest of these tiresome insects, living in the middle of the fruit from which it 

 takes its name, and giving rise to the condition which is termed " maggoty." The 

 larva is a round, fat, white grub, which may too often be found in the interior of an 

 apparently sound and ripe apple, and which gives to every part which it has touched a 

 very bitter and nauseous flavor, like that of a worm-eaten nut. None of the Tortricidae 

 are of very brilliant colors, the Oak-leaf Roller being one of the most conspicuous. 

 The fore wings are dark grayish brown, striped transversely with a darker tint. On the 

 outer part of each wing there is a dark brown space streaked with golden bars. The 

 hind wings are simple dusky brown.
