some
of
the
most
interesting
insects
on
the
____________________
Earth
.
There
are
more
than
17
,
000
different
kinds
of
butterflies
!
Butterflies
come
in
all
shapes
and
sizes
.
Butterflies
go
through
four
main
stages
of
life
.
The
first
stage
is
the
egg
stage
,
followed
by
the
larva
stage
.
As

____________________
,
the
future
butterfly
____________________
as
much
as
possible
.
As
it
grows
,
it
sheds
its
outer
skin
,
or
exoskeleton
.
This
may
happen
four
or
five
times
.
After
a
few
weeks
,
the
caterpillar
enters
the
next
stage
of
its
life
,
the
chrysalis
stage
.
In
the
chrysalis
stage
,
the
caterpillar
will
liquefy
into
a
soup
of
living
cells
.
Then
,
it
will
reorganize
into
a
butterfly
,
and
the

is
complete
.
In
later
parts
of
the
chrysalis
stage
,
you
can
see
the
forming
butterfly
through
the
chrysalis
.
When
the
butterfly

from
the
chrysalis
,
it
pumps
its
wings
to
send
blood
through
them
so
that

Most
butterflies
only
live
a
couple
of
weeks

just
enough
