MAINE AGRICULTURAL EXPERIMENT STATION. 



The Cigar Case-Bearer. 

 (Coleophora fletcherella.) 



The caterpillars infest mainly the leaves, but in the spring 

 they may also be found on the buds and the young fruits. The 

 full grown caterpillar is reddish orange and averages 1-5 of an, 

 inch in length. The case, as it is made in the fall, is a minute 

 flattened curved structure composed of portions of the upper 

 and lower skins of the leaf. In the spring a second case (fig. 

 23) is made, which is longer, cylindrical or cigar-shaped, in 

 which the larva pupates. The adult insect which emerges from 

 the pupa during June and July is a small, steel gray moth 

 expanding less than ^ an inch.

REMEDIES. 



This insect can be kept in check by arsenical sprays, the first 

 to be applied as soon as the cases are noticed on the opening 

 buds. A second and perhaps a third application may be neces- 

 sary at intervals of 4 to 7 days on badly infested trees.
