Allied
to
the
milkweed
is
another
plant,
the
dogbane
(Apocynum),
which
has
a
similar
trick
of
entrapping
its
insect
friends.
Its
drooping,
fragrant,
bell-shaped
white
flowers
and
long
slender
pods
will
help
to
recall
it.
But
its
method
of
capture
is
somewhat
similar
to
the
milkweed.
The
anthers
are
divided
by
a
V-shaped
cavity,
into
which
the
insect's
tongue
is
guided
as
it
is
withdrawn
from
the
flower,
and
into
which
it
often
becomes
so
tightly
wedged
as
to
render
escape
impossible.
I
have
found
small
moths
dangling
by
the
tongue,
as
seen
in
the
illustration
below.
