Think of over a quintillion of flies
| to torment us in the fall just because
| a solitary female escaped the winter!
Fortunately such numbers are never
rallied for many flies of each gener-
alton never reach maturity. Were
| flies to breed uninterrupteilv for the
entire season the individuals of the
| latter generations would no have
| room to exist; the earth would be
| covered with a solid mass of flies.
Lack of breeding places is the only
| reason why house flies do not occur
| by the millions where one occurs
/ now
The one hundred and twenty eggs
| laid by the house fly are all placed
in fresh horse manure. If that can
| not be found and human excrement
| is available it is made the second
| choice Within a day the eggs have
Matched to maggots which proceed TO
| feed on this filth. Five days Of feed
| ing sufices to nourish them 20 their
| full growth whereupon they change
l to pupae This change is accom-
| plished by a shrirkage, toughening
| and darkening of TIE maggot's skin
Within this skin the maggot changes
over to the adult fly, processwhich
takes about five days more, but dur
ing which no food is consumed. From
what we have just observed concern
ing the food of the maggot it will be
seen that the bodies of house flies
are merely transformed excrement.
1t is not an infrequent matter to
III find manure alive with wrigg'ing
ii maggots. Hence a single stable or
II an uncovered clubhouse is abundantly
= able to supply flies to a great nan

The adult fly is essentially house
insect. When it has deposited lis
eggs, or even before, it seeks to en-

Flies are indiscriminate feeders
They may be found feasting in pan
try or on table, as well as revel;na
IN the foulest matter. The mouth
parts of the fly consist of pump Ike
arrangement connected with the sro

able to suck up liquids but posses

much more food than they actuall,
