Venus Fly Trap
Dionaea muscipula
•
Located in poor soil
in southern swamps
of the US.
•
These poor soil
swamps have lots of
water, but little
nutrients and
minerals that the
plant needs–
specifically nitrogen.
Venus Fly Trap
Dionaea muscipula
•
Nitrogen is found in
the air but only
makes it into the soil
in a form that plants
can absorb when
things die and rot.
Venus Fly Trap
Dionaea muscipula
•
In these southern
swamps there is too
much acid for
decomposing fungi
to survive and break
down living things,
so when things die
they rot VERY
slowly and give off
little nitrogen.

Dionaea muscipula
•
Plants that live in
these swamps need
to get nitrogen other
ways and
carnivorous plants
like the Venus fly
trap do this by
capturing flies and
other insects.
Venus Fly Trap
Dionaea muscipula
•
The trap attracts
flies with a rotting
smell and red color
simulating flesh that
flies eat
•
The movement of
the fly stimulates
rapid cell growth in
the specialized
leaves and the trap
closes.
Venus Fly Trap
Dionaea muscipula
•
The trap doesn’t
close all the way at
first, allowing insects
that are too small to
escape.

•
Then the trap closes
and the plant
releases digestive
fluids, slowly eating
the insect.

When finished, the

rain or wind washes
the skeleton of the

plants
use sticky sap to

Similar Species– Pitcher Plant

Pitcher plants
attract insects with
scents and then the
insects fall into a
watery pool where
they drown and
then are slowly
digested for their
nitrogen.
The Venus Fly Trap, scientifically known as Dionaea muscipula, is a unique carnivorous plant found in the southern swamps of the US. It is a eukaryotic, multicellular autotroph that thrives in poor, nutrient-deficient soils by capturing insects for essential nutrients like nitrogen. Its trapping mechanism involves specialized leaves that close upon insect stimulation, aiding in digestion. This plant's adaptation showcases a remarkable evolutionary strategy for survival.
