282 THE INSECT WOKLD. 



When it has reached its full size, it abandons its abode, pierces 

 through the stuff which covers the hair, and constructs for itself 

 with this stuff a case of silk, open only towards the end where its 

 head is. At the beginning of April it shuts its case, and changes 

 itself into a chrysalis. 



We can only here mention some of the phytophagous species, as 

 the Cherry-tree moth (Tinea cerasiella), the Hawthorn moth 

 ( Tinea cratcegella), the Burdock moth ( Tinea lapella),a,nd. the Rustic 

 moth ( Tinea rusticella). 



The caterpillars of the CEcophorce resemble whitish worms. 

 They attack the leaves, the blossoms, the bark, and certain parts 

 of the fruit of trees. Some of these hollow out for themselves 

 galleries in eating the fleshy part ; others also make galleries, but 

 only in the cuticle of the tree or in the tenderest part of its 

 bark. Some, again, shut themselves up in one or many leaves 

 rolled like a trumpet, while others keep at the summits of plants, 

 whose leaves they bind together in a parcel with threads. And, 

 lastly, some devour the stones of fruits, such as that of the olive. 



The moths of these caterpillars are very small, and generally of 

 brilliant metallic colours. They are to be found in the woods, and 

 still more in the orchards, from the beginning of June till the 

 month of September. 



The (Ecophora are very slim and elegantly formed. Their 

 anterior wings, which are very narrow, are often ornamented with 

 silvery longitudinal lines, the posterior wings exactly resembling 

 two feathers. 



The caterpillars live and metamorphose themselves in portable 

 cases, which they manufacture from the membraneous portions 

 of leaves, whose flesh alone they eat. These cases are generally 

 of a brown colour, resembling a dead leaf. They are attached 

 perpendicularly under the leaves of many trees, but often under 

 those of fruit trees. 



Certain species of (Ecophorce have cases partly covered with 

 loose pieces only slightly attached, formed of portions of leaves, 

 and arranged in such a way that Reaumur compares them to the 

 furbelows which ladies used formerly to attach to the bottom of 

 their dresses.
