4. A fly is an insect and insects are
special animals. Flies go through
a complete metamorphosis,
going from egg to larva or
maggot, then pupa to adult
stages within a week. They look
very different in each stage. All
the stages together are called a
life cycle.

Did you know?
There are over
40,000 known
species of flies.
And you thought
there was only
one kind, the
annoying kind.

5. The common house fly
belongs to the group of flies
known as the filthfly. They
were given their name for
their habit of laying their eggs
in moist, decaying organic
matter, particularly manure
and garbage.
Now lets see how they grow.

Did you know?
The fly regurgitates
or vomits on the
food to chemically
break down the
substance before
sipping up their
meal through their
straw-like
mouthparts.
GROSS!!

6. The adult female fly can lay
up to 500 eggs in batches of
75 to 100 over a period of 3
to 4 days. If temperatures
are high, eggs may hatch
within 8 hours, otherwise it
may take 1 to 2 days for
them to hatch.
Now lets look at the
different stages of growth.

Did you know?
The common
house-fly only
lives for 15-25
days

Stage One -First the adult
female fly, which is bigger
than the male fly, lays
hundreds of tiny eggs.

8. 4-7 days
since eggs
were laid
BACK GO
Stage 2 -Here the eggs
have hatched into larvae
or another name for them
is maggots.The maggots
feed on the organic
material in which they
were laid.

9. 10-20
days since
eggs were
laid
BACK GO
Stage 3 –When the maggots stop
feeding they burrow into the dry
surrounding areas for protection.
This is where they pupate.During
the pupastage, change takes
place.

GOBACK
Stage 4 –When ready, the fully developed
fly comes out of the pupa. The mature
adult fly is now ready to reproduce and
continue its life cycle.

12. The easiest way to keep flies out of your
home is to keep things clean. Don’t leave
food lying around, make sure to take out
the garbage on a regular basis and wipe
up messes straight away.

13. Life cycle: the series of changes of form
and activity that a living organism
undergoes from its beginning through to
maturity.Back

14. met·a·mor·phous
metamorphous: the transformation of an
insect from an immature form or larva to
an adult form in distinct stages. Back

15. lar-vae
larvae: the wingless immature worm-
shaped form of many insects that
develops into a pupa or chrysalis before
becoming an adult insect. Back

16. Mag-got
Maggot: the worm-shaped larva of
various members of the fly family, found
in decaying matter.Back

17. pyoo-pate
pupate: become a pupa, to develop from a
larva into a pupa Back

18. pyoo-pa
pupa: an insect at the stage between a
larva and an adult where the insect is in a
cocoon, stops feeding and undergoes
changes. Back

19. F-il-th
Filth: dirt or rubbish that is disgusting or
excessive. Back

Ways of working
Students are able to
•draw conclusions that are supported by evidence, reproducible data and
established scientific concepts.
•reflect on learning to identify new understandings and future applications.
Knowledge and Understanding
•Scientific ideas can be used to explain the development and workings of
everyday items.
Life and living
Living things have features that determine their interactions with the
environment.
• Living things can be grouped according to their observable characteristics
e.g. flies are insects
• Reproductive processes and life cycles vary in different types of living things
e.g. flies develop through stages
• Living things have relationships with other living things and their environment
e.g. the relationship between a fly and its surroundings is mutually beneficial
