LEAF-BUGS. 65 
Calocoris rapidus Say, which is very commonly seen upon 
the heads of such composite flowers as golden rods, thistles, 
and others, is illustrated in Fig. 54. This insect, well named 
rapidus on account of its rapid motions, belongs to another sub- 
family, Phytocoraria of the Capside, for which reason it has 
been illustrated. Usually it is neither injurious nor beneficial, 
but at times causes considerable injury to the sugar beets. An- 
other European species is illustrated in Fig. 55. 
Another sub-family, Loparia, contains some of the brightest 
colored species of true bugs, in which red, orange, and black 
colors predominate. Some of the bugs belonging here are very 
common and are found in large numbers upon the bushes of 
wild blackberries and gooseberries during the month of July.

Lopidea media Say, illustrated in Fig. 56, is very abundant ; 
it is a rather brightly colored bug, being yellowish-red marked 
with black. Though plant-feeding insects, they have developed 
a taste for human blood. While camping for a few days upon 
an island largely covered with wild gooseberries, it was fre- 
quently observed upon these plants, where it seemed to feed, like 
all its near relatives, upon the sap. But soon after the persons 
living in the camp were bitten very frequently by these bugs, 
and their bite caused considerable pain and swelling of the 
bitten part. The bugs would imbibe blood until barely able to 
fly. But as if to prove their love for human blood they even 
invaded the tents, and large numbers had to be killed to prevent 
them from biting.
