282 THE INSECT WORLD. 
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 crategella), the Burdock Moth (Tinea lapelia), and the 
Rustic Moth (Tinea rusticelia). 
The caterpillars of the Ccophore 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 Cicophore 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 membranous portions of 
leaves, whose flesh alone they eat. These cases are generally of 
a brown colour, resembling a dead leaf. They are attached per- 
pendicularly under the leaves of many trees, but often under those 
of fruit trees. 
Certain species of Gicophore have cases partly covered with 
loose pieces only slightly attached, formed of portions of leaves, 
and arranged in such a way that Réaumur compares them to the 
furbelows which ladies used formerly to attach to the bottom of 
their dresses.
