The document provides an overview of the insect order Lepidoptera, which includes butterflies and moths, detailing their anatomy, feeding behaviors, and habitats. It highlights that there are approximately 150,000 species, with 28,000 being butterflies, and describes their feeding habits, such as butterflies using a proboscis to sip nectar. Additionally, it covers dragonflies and damselflies, noting their predatory nature and preference for aquatic habitats.

LEPIDOPTERA

3. BUTTERFLIES
 Gaudy diurnal insects with
sealed wings that are large in
proportion to body, antennae
knobbed out never hooked at tip,
and close together at base. Often
held together above body.

4.  Butterflies and moths belong to the Order Lepidoptera.
 It comes from the Greek word Lepidos which means ‘scales’
and ptera meaning ‘wings’
There are more types of butterflies and moths than there are
of any other type of insects except beetles.
 It is estimated that there are about 150,000 different species
of these order. 28,000 of these are butterflies and
the rest are moths.

5. ANATOMY
Like all insects, they have :
six (6) jointed legs,
3 body parts (the head, the thorax and the abdomen)
A pair of antennae
Compound eyes
And exoskeleton

7. The butterfly’s body is covered by tiny sensory hairs.
The four (4) wings and the six (6) legs are attached to
the thorax which also contains the muscles that make
the legs and wings move.

8. FEEDING BEHAVIOR
Caterpillars spend most of their time eating leaves
using strong mandibles (jaws).
A caterpillar’s first meal however, is its own eggshell.
A few caterpillars are meat – eaters.
The larva of the carnivorous harvester butterfly
eats wholly aphids.

9. Butterflies and moths can only sip liquid food using
a tube – like proboscis, a long flexible ‘tongue’
This proboscis uncoils to sip food, and coils up
again into a spiral when not in use.
Most butterflies live on nectar of flowers.

10. HABITAT
Butterflies are found all over the world and in all
types of environments: hot and cold; dry and
moist at sea level and high in the mountains.
Most butterflies are found in tropical rainforests.
Most migrate in order to avoid adverse
environmental conditions.

11.  Common Name:
Grey Pansy
 Scientific Name:
Precis atlites

13. ORDER ODONATA

15. DRAGONFLIES & DAMSELFLIES
 At rest, damselflies hold
their wings together above the
body is diverging, dragonflies
hold them horizontally.
 Dragonflies are also called
darner, devils' arrow, and
devil’s darning needle.

16. ANATOMY
 Dragonflies have long, thin and generally colorful bodies,
large eyes and two pairs of transparent wings.
 As with other species of insects, the dragonfly also has
six legs but it is unable to walk on solid ground.
 In flight, the adult dragonfly can propel itself in six directions -
upward, downward, forward, and side-to-side.

18. FEEDING BEHAVIOR
Dragonflies are major predators that eat mosquitoes
and other small insects like flies, bees, ants, wasps and
very rarely butterflies.
As a larva, it eats tadpoles or small fish.
Dragonflies are carnivorous in both larval and adult
stages.

19. HABITAT
Dragonflies are most often found near water and
usually remain within a few miles of the place where
the eggs are hatched.
Female dragonflies deposit their eggs insert them
into aquatic plant or mosses.
