9. About DRAGONFLY
• A dragonfly is an insect belonging to the order Odonata, the suborder
Epiprocta or, in the strict sense, the infraorder Anisoptera because
the hindwing is broader than the forewing.
• It is characterized by large multifaceted eyes, two pairs of strong
transparent wings, and an elongated body.
• 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.
10. Life Cycle of DRAGONFLY
• Female dragonflies lay eggs in or near water, often
on floating or emergent plants. When laying
eggs, some species will submerge themselves
completely in order to lay their eggs on a good
surface. The eggs then hatch into nymphs.
• Most of a dragonfly's life is spent in the nymph
form, beneath the water's surface, using extendable
jaws to catch other invertebrates (often mosquito
larvae) or even vertebrates such as tadpoles and
fish.
11. • They breathe through gills in their rectum, and can
rapidly propel themselves by suddenly expelling
water through the anus. Some nymphs even hunt
on land, an aptitude that could easily have been
more common in ancient times when terrestrial
predators were clumsier.
• The larval stage of large dragonflies may last as long
as five years. In smaller species, this stage may last
between two months and three years. When the
larva is ready to metamorphose into an adult, it
climbs up a reed or other emergent plant.
12. • Exposure to air causes the larva to begin breathing.
The skin splits at a weak spot behind the head and
the adult dragonfly crawls out of its larval
skin, pumps up its wings, and flies off to feed on
midges and flies.
• In flight the adult dragonfly can propel itself in six
directions; upward, downward, forward, back, and
side to side. The adult stage of larger species of
dragonfly can last as long as five or six months.
14. Flight Speed of DRAGONFLY
- Dragonfly’s flying speed is at nearly 60 miles per
hour (97 km/h) in a rough field measurement.
- The greatest reliable flight speed records are for
other types of insects.
- Large dragonflies like the hawkers have a maximum
speed of 10–15 meter per second (22–34 mph) with
average cruising speed of about 4.5 meter per
second (10 mph).
19. About RUBBER TREE
• Rubber Tree is a tree belonging to the family
Euphorbiacea. It is the most economically important
member of the genus Hevea.
• It is of major economic importance because the milky
latex extracted from the tree is the primary source of
natural rubber.
• In the wild, tree can reach a height of up to 100 feet
(30 m).
• In plantations, the trees are kept smaller, up to 78 feet
(24 m) tall.
24. Harvest of Latex
• Harvesters make incisions across the latex
vessels, just deep enough to tap the vessels without
harming the tree's growth, and the latex is collected
in small buckets. This process is known as rubber
tapping. Older trees yield more latex.
26. Fishes
There are dragonfishes with small
and medium sizes in the river
which is at our site. They shelter
between the roots of the trees.

28. ECOSYSTEM
From what I observe in the site is that living things rely
on each other for survival. There is no living thing in
existence that is self-sufficient. I appreciate with the
nature and its ecosystem. The ecosystem is not just a
biological community fighting for survival but rather, a
community that interacts with each other that results in a
balanced natural ecosystem. However when this balance
is disturbed by human activities, it may result in the
extinction of endangered species. I predict that if the
ecosystem is continually unbalanced, one day it could
mean the extinction of mankind. Everyone should be
more cautious of nature and take it serious so that the
ecosystem can continue goes without any threaten.
