BELL-MOTHS; LEAF-FOLDERS. 223 
SUPER-FAMILY TORTRICINA OR BELL-MOTHS. 
These moths are generally small, with broad fore-wings 
usually squarely cut off. The front margin ofthe wing curves 
forward very strongly near the base of the wing, and at rest 
the broad fore-wings fold above the body like a roof. The 
wings are usually of the color of the body and frequently 
without markings. Most of the caterpillars, which, how- 
ever, vary greatly in habits, are leaf-rollers, and this habit 
suggested the name ‘‘Tortrix.’’ The leaves are rolled to- 
gether in various ways, and are not simply used as shelter 
but also as food, and in many cases such a leaf is at first 
the nest for an entire brood of caterpillars. 
THE FAMILY TORTRICIDAZ OR TYPICAL LEAF-FOLDERS. 
Considerably more than one hundred different kinds of 
our moths belong to this family. Most of their caterpillars 
_are decidedly injurious and not a few are found upon our 
' fruit-producing plants. 
THE CRANBERRY LEAF-FOLDER. 
(Teras oxycoccana Pack.). 
Only a single specimen of this insect was found near 
Park Rapids, showing, however, that the moth exists in our 
state, perhaps in large numbers. If the growing of cran- 
berries in’ our numerous bogs, some of which are well 
adapted to this purpose, should become much more of a 
business than it is now there is but little doubt that this in- 
sect will prove destructive. It is a small moth, spreading 
nearly three-fourths of an inch across the wings, with 
uniform reddish-brown fore-wings with a peculiar silky 
lustre; the red tint is caused by scattered bright-red scales. 
The hind-wings are glistening gray; the body is of a dark
