appeared August 3. These moths, undoubtedly, like cerasivorana, lay 

 eggs that pass the winter. 



The eggs are laid in clusters on the bark and on the leaves of the trees. 

 In Fig. 75 is shown an egg mass on the bark of an apple tree, collected 

 in the field at East Bethany. The cluster is usually oval, rather fiat, 

 and green in color. When hatched the eggs are shining white. Sanderson 

 and Jackson found the average number of eggs deposited by a single 

 moth to be 117. 



THE UGLY-NEST LEAF-ROLLER 



{Ar chips cerasivorana) 



This is another species of leaf-roller that was rather abundant last 

 season. It works on the cultivated cherry and on the wild chokecherry. 

 The nests are very conspicuous because they are large and sometimes 

 numerous. The nests are made by the larvse fastening 

 together all the leaves and twigs on one branch. When 

 the pupae change to moths they work out of the tangled 

 mass and their empty skins may be seen projecting from 

 all sides of the nest. Last season the moths appeared in 

 great numbers in our cages during the latter part of June. 

 The eggs. — So far as the writer is aware, the egg masses 

 have never been figured. The eggs were found in 1900 by 

 C. M. Weed on the stems of the chokecherry near the 

 ground. 



Some moths that appeared in our cages in June were fed 

 on sugar, and on July i egg masses were found fastened to 

 the sides of the cages. Some pieces of branches of cherry 

 were then placed in the cages and many eggs were deposited 

 on the bark (Fig. 76). These eggs, deposited July 2, 

 are still (January, 19 12) inoiir cold house unhatched, and 

 will of course remain so until next spring, there being only

 nest leaf -roller '^^^ ^SS masses are usually flat, long, and narrow, and 

 are rather reddish yellow in color at first, being somewhat 

 conspicuous on the bark. Later they turn brown and become hard to 

 distinguish. Occasionally a small mass, more or less circular in out- 

 line, will be deposited. Half a dozen average masses measured from 

 three tenths to three fifths of an inch in length and about one tenth of 

 an inch in width (Fig. 77). 



The moth. — The moth has bright ocher-yellow wings that expand from 

 four fifths of an inch to over an inch (Fig. 73).
