BUGS 
(Hemiptera) 
LV IRVOUS TO OUR CULTIVATED SPLANTS: 
OTTO LUGGER. 
The destructive species of Butterflies, Moths, and Beetles 
found in Minnesota have been described in previous reports, and 
especially have those been mentioned which are injurious to fruit- 
producing plants. In every -case a description and an illustra- 
tion of the culprits was given, as well as the best remedies to 
counteract their injuries or to prevent entirely losses caused by. 
them. In this report “Bugs” will be considered in the same 
manner, and to make the report of greater value to farmers 
and students, the insects belonging to the order of Bugs 
(flemiptera) will be arranged in such a manner as to indicate 
their classification as usually adopted. To do this more thoroughly 
a few only moderately injurious as well as some beneficial species 
have been included, for it is wise that the fruit-grower and farmer 
should not only know his enemies, but also his friends, as this 
knowledge will enable him to combat the former and to protect 
the latter. 
ORDER’ OF BUGS, PLANT-LICE, BARK-LICE ETC. 
(Hemiptera). 
The perfect, adult, or winged members of this order of in- 
sects possess four wings; in one sub-order, (Heteroptera), the 
first pair of wings are thickened at the base and have thinner 
extremities, which overlap on the back (Fig. 1); im another 
sub-order, (Homoptera), the first pair of wings are of the same 
thickness throughout, and usually slope at the sides of the body 
(Fig. 2). The mouth-parts are formed for sucking, (Fig. 3), 
and the metamorphosis is incomplete (Fig. 4).
