The Life Cycle of
the Fly
By: Bailey
 The eggs of a fly are
about 2.1mm.
 Are a creamy white
 The eggs are piled in
small groups.
 The maximum
temperature of an egg
can be 25c – 30c.
 Eggs must stay smooth
or they will not hatch
 The female fly can lay up
to 500 eggs

Fly Larva can be 3-9 mm long.
Usually a whitish color by the
head.
Head has one pair of dark hooks.
Like warm weather.
Dumb bell shape and are soft.
Attach them selves to rocks and
wood
Are a food for birds and reptiles
Before they are pupas they are
about 15 -20 mm in size
some fly larvae eat other larvaes
Are called “eating machines”
because they can eat quite a bit
Larvaes can consume 60cm of a
human body
Fly larvae molt (shed) their skin
twice before going on to the next
stage of their life
When ready to change into their
next stage they go about 50ft to
find a cold, dry place to change
 Goes underground when
changing into an adult fly
 About 8mm long while in
pupa stage
 Can be yellow, red, brown or
black
 While changing into a adult
fly. They go in sacs called a
ptilinum
 uses its head to break out of
the ptilinum
 Have reddish brownish skin
when becoming an adult

Feeds on body fluids
Female adult flies lay 75-100 eggs
Can travel 20 miles per day
6-7 mm long
Have markings on the sides
Wide space in between eyes
Usually live 15-25 days
Female fly will lay 400 eggs in her
whole entire life
If not have food they only live 2-3
days
The only way female flies are able
to have babies if they have food to
eat
Female flies are larger than male
fly
Possible for them to live for about
2 months
A fly up
close
 Eggs take one day to hatch
 Eggs look like grains of rice
 Scientists tried seeing how much the fly
population would grow. By August there
were 191,010,000,000,000,000,000 flies
in total.
 This is the end of my
slide show. I hope
you enjoy it and learn
a little something that
will come in handy
some day.
