206 Bugs, Cicadas, Aphids, and Scale-insects 
hatch in about a week and the young become full grown in about three months 
moulting five times during growth, but active and capable of “finding” for 
themselves from birth. In the northern states there is but one generation 
a year. The disagreeable bedbuggy odor is produced by a secretion of 
small glands opening, in the adult, on the under side of the body. Another 
species of Acanthia attacks chickens, pigeons, swallows, and bats, and 
Lugger found this species, A hirundinis, or another similar one, attacking 
in daytime the pupils in a school in western Minnesota. The best remedy 
is the free application with a quill-feather of a saturated solution of corrosive 
sublimate (Poison!) in alcohol to all cracks and crevices in infested bed¬ 
steads, walls, floors, and ceilings. When bedbugs cannot be found hiding 
in bedsteads in daytime and yet mysteriously appear every night, it is often 
because they drop from the ceiling.

In this family belong several small inconspicuous insects called flower- 
bugs, which do much good by their persistent preying on noxious insects. 
The best-known species is the insidious flower-bug, Triphleps insidiosus, 
which preys on the chinch-bug. Another species is Lyctocoris fitchii 
(Fig. 286), which preys on the larvae of certain destructive wood-boring 
beetles. 
The remaining families, eleven, of American bugs find their food and 
drink, for the most part, in the juices of living plants. Like the blood¬ 
sucking bugs, they need for their feeding, and have, a well-developed suck¬ 
ing-beak. From the tip of the sheath (labium) can be thrust out the foul
