2. Pond Hawk Dragonfly/ picture by M iroslow fials
There are 5,574 recognized species of dragonfly. The Pond Hawk Dragonfly also goes by the
names of green Jacket or Common Pond Hawk. These are probably one of the most easily
found and observed of all the dragonflies in Northwest Missouri. I come across them quite
frequently, and I am always excited to see them, you can find them near pound, rivers, lake,
and park areas, They are primarily a species of the Eastern United states, and southern Ontario

3. How Long do Dragonflies Live?
• The Common Pond Hawk Dragonfly is an insect that has inhabited the earth for
almost 300 million years to be exact. There are more than 5000 species of
dragonflies that exist today. There are many people who believe that these insects
live only for a day. This however is not true. At the shortest the life cycle of a
dragonfly from egg to the death of the adult is about six months. There are even
dragonflies that live for several years as aquatic larvae before they emerge and
live for a few months as adults. Most dragonflies don't die of old age but are
caught by predators. Even if they do survive, they still don't live much longer than
a few months.
A surprising and interesting fact about the dragonfly is that, they will spend only a
very short part of their life span as actual adult dragonflies. They will live as
nymphs for up to four years, molting their skin between 8 to 17 times depending
on the species, and finally when they mature into adults, they can only live for a
few months.

7. Dragonflies possess six legs (like any other
insect), but most of them cannot walk well.
Dragonflies are among the fastest flying insects
in the world. Dragonflies can fly backwards ,
upside down, and change direction in mid-air
and hover for up to one minute. Wow cool.

SCIENTIFIC NAMES ARE ALWAYS TWO WORDS. THE FIRST PART OF THE NAME
(GENUS) IS ALWAYS CAPITALIZED. THIS LETS US KNOW THAT IT IS THE GENES. THE SECOND
NAME IS ALWAYS IN LOWER CASE AND IS USUALLY DESCRIPTIVE OF THE INSECT IN SOME
MANNER. BECAUSE THESE WORDS ARE IN LATIN THEY ARE ALWAYS ITALICIZED OR
UNDERLINED.

• Adult Pond Hawk Dragonfly are known for having three major body
regions, six legs, one pair of antennae, and two pair of wings.

Antennae are used by Pond Hawk Dragonfly as a major sensory
devices, especially for smell, and can be adaptive for the insect in
many ways. Pond Hawk dragonfly don’t have noses like human
and other mammal do so they smell and breath through their
antennae. Can you say weird?

19. Two Examples of the Pond Hawk DragonflyTwo Examples of the Pond Hawk Dragonfly
MouthpartsMouthparts
.
The Pond Hawk Dragonfly mouthparts are also highly modified for
eating insect. They use them for chewing, or biting, or sucking, which are
a few examples. Mouthparts of an immature nymph differ from those of
the same in its adult stage.
Paulson 2009 insect poster drawings

20. Dragonfly nymph in the earliest stages have chewing mouthparts. Adult dragonfly
have mouth parts mostly used for piercing and sucking, and for the male Pond Hawk
Dragonfly its also used for combat with other male dragonfly.
Dragonfly nymph is biting and eating a tadpole in picture
below
Dragonfly is using the sucking motion on his prey by sucking
his blood out of his body .
• Pond Hawk Dragonfly have tube-like mouth to suck blood or plants juice. They also have biting mouth,
Dragonflies, Orthopteroid ... have large mandibles which they are used solely in combat with other males

21. Adult Pond Hawk dragonfly have large mandibles which they are used solely in combat with other males
• But in order for nymph to catch prey ,the nymph of a Pound Hawk dragonfly have a mouthpart, called a labium which is folded
under the head, then when the nymph approaches its prey the labium swings forward and grab it.

22. The three techniques Pond Hawk Dragonfly use when hunting, and catching prey
• Motion camouflage is a dynamic type of camouflage by which an attacker can approach a target while appearing to remain
stationary from the perspective of the target. The attacker chooses its flight path so as to remain on the line between the
target and some landmark point. It therefore stays near the landmark point from the target's perspective. The only visible
evidence that the attacker is moving is its looming, the change in size as the attacker approaches. First discovered in Pond
Hawk Dragonfly.

23. The Pond Hawk middle body region is called a Thorax

24. Pond Hawk legs usages
Like the mouthparts and antennae, Pond Hawk Dragonfly legs
are quite variable in form and function and reflect their lifestyle.

25. The Pond Hawk Dragonfly abdominal region help him to achieve acrobatically stunts

26. Pond Hawk Dragonfly mate through their abdomen.
The picture on the bottom left, looks as if they have made a heart shape
• Mating takes place near water, Pond Hawk Dragonflies are unique in that the male has two sets of sexual organs.
It isn’t known why they have evolved this way, but the “primary organ” is on the ninth segment of the abdomen
and the “secondary organ” is located on the ventral side of the second segment. In mating, a male first grabs a
female by her pro-thorax or the back of her head with his two claspers and holds on. Just before copulation he
curls his body so he can transfer a packet of sperm directly from the primary organ to the secondary. The female
in turn curls her body around until her sexual organs come in contact with the male’s secondary organs. This
forms a shape that’s unique in the insect world and referred to as the “wheel position,” but it really looks more
heart-shaped than round.

30. Inside the Pond Hawk Dragonfly you will find their
system for respiration, circulation, nerves, and
digestion, but their system has little resemblance to
human or other mammals.

Pond Hawk Dragonfly Internal Anatomy

31. Digestive system
• The digestive system is a tube that opens at the mouth
and empties at the tail end of the Dragonfly. It is
divided into three parts called the foregut, midgut, and
hind gut. In Dragonfly, the foregut acts as a crop to
carry, or hold liquids which can be regurgitated later.

the West. Princeton University Press. ISBN 0-691-12281-4.

32. Circulatory System
• The circulatory system is not composed of a central heart, veins
and arteries which circulate blood cells and transport oxygen. The
dragonfly circulatory system is a simple tube down the back which
is open at both ends and slowly pulses body fluids and nutrients
from the rear of the dragonfly to the head.

Damselflies of the West. Princeton University Press. ISBN 0-691-12281-4.

33. Pond hawk Dragonfly have a less centralized nervous system than humans.
The nerve chords run along the ventral or bottom aspect of on dragonfly.
The brain is divided into two main parts. The largest lobes control important
areas such as the eyes, antennae, and mouth parts. Other major
concentrations of nerve bundles called ganglia occur along the nerve chord
and usually control those body functions, closest to it .

Damselflies of the West. Princeton University Press. ISBN 0-691-12281-4.

34. The Pond Hawk Dragonfly respiratory system, is composed of air sacs and tubes
called tracheal. Air enters the tubes through a series of openings called spiracles
found along the sides of the dragonfly body. Like in this drawing by Paulson
below: The largest spiracles are usually found on the thorax where greater
musculature from wings and legs require more oxygen. There are no spiracles on
the head.

36. Pond Hawk Dragonfly Life Cycle
is known as Metamorphosis.
• The Pond Hawk Dragonfly has a diverse order
of three life cycles. These life cycles are called
metamorphosis, because of the changes of
shape that the insects undergo during
development.

37. The Nymphs resemble adults, but without wing, or size, or without metamorphosis

40. • Pond Hawk Dragonfly have been on earth for many of years, fossils of very
large Pond Hawk Dragonfly ancestors were found in this Protodonata and
are back from 325 million years ago, in the upper carboniferous rocks;
These pond Hawk Dragonfly had wing span of up to 750 mm. There are
about 3000 species of Anisoptera in the world today. Most are tropical,
with fewer species in the temperate regions .
