Ten of these species devour the root and crown of the plant, all 
Coleoptera but one, which is the larva of a moth. The leaf and its 
petiole are attacked by two of the Hymenoptera, by all the Lepid- 
optera except two, by the single dipteron, by eight of the Coleop- 
tera, by both of the Orthoptera, by five of the Hemiptera, and by 
the red mite. ‘The flower and fruit are damaged by the ant, the 
stalk-borer, one of the leaf-rollers, by a snout beetle, by two plant 
bugs, and by the myriapod. 
Less than a fourth of the known enemies of the strawberry really 
seriously injure it in a way to demand earnest effort for their sup- 
pression, the remainder being too few in number or too local in 
their occasional outbreaks, to do more than threaten the crop with 
possible future mischief. Of these enemies of the strawberry of the 
first class, but two devour the leaf—the strawberry slug and the 
leaf-roller; four attack the roots—the white grubs and the three 
root-worms; one bores the crown—the crown-borer; and two injure 
the fruit—the tarnished and the dusky plant bugs. 
In the following classified list, the species are arranged with refer- 
ence to their systematic relations, and the first-class insects are 
distinguished by italics. The common names given are usually 
those by which they have been most generally known in Illinois. 
The references in parenthesis, after the technical names, are to the
