Evolution of butterfly and moth
How ??
From fossil(Archaeolepis
Mane)
From Jurassic period
(190 million years ago)
Similarities
Some scientist said that, moth or butterfly did not
evulated from any organism, but it contunually exist till
now.They undergo adaptation
based on the climate changes.

• Moths are split into two sub-orders • the Macrolepidoptera (larger moths)
• and the Microlepidoptera (small or micro moths).
• The life-cycle similar to that of butterflies. T• hey are holometabolous insects
• Also known as metamorphosis. • Some butterflies live only for a couple of
weeks• While some others live longer up to a
couple of months.
egg
caterpillar

chrysalis
Caterpillars:~different species eats
different plant~Do not have to drink
water. They get all the water they need from
their food.~moth larva feeds on
protein-based materials of fur, wool, and cotton.
Feeding modeFeeding mode
Moth : ~ does not eat anything(use nutrient consumed at
larval stage)~ fruit
Butterflies ~ nectar
~ tree sap~ rotting fruit
~ dung~ decaying flesh
~dissolved minerals in wet sand or dirt~ need more sodium than provided by nectar, thus
attracted to sodium in salt and human sweat.
Differences between butterflies and Differences between butterflies and mothmoth
Are they migrate ?
What is migration ?
The mass movement of an animal species across many
miles in order to escape unfavorable conditions.
Some butterflies, such as the monarch, may migrate
thousands of miles in order to avoid winter conditions.
Other types of butterflies may only migrate a relatively
short distance
How do they migrate ?
• Butterflies and moths often seem to
flutter or bumble about in a haphazard
way, are capable of long-distance
migration.
•Many of our familiar butterflies and
moths migrate. Some such as the Red
Admiral, Painted Lady and Clouded
Yellow butterflies and the Humming-
bird Hawk-moth and Silver-Y
What make them migrate ?
•Lepidopteran migration is usually seasonal, moving to
escape dry seasons or other disadvantageous conditions
•Butterflies escape cold weather is by migrating to a warmer region.
• They may migrate regarding to the disturbance of their living place.
•Monarchs are considered the long-distance champions of butterfly
migration, traveling as many as 4000 miles round trip.
• For moth, the majority of them immigrants around the world, move in a
northerly direction.
How do they fly?
• Lepidopterans have strong muscles in their thorax which force their wings
up and down on a fulcrum basis.
•They fly mostly by flapping their wings.
• In some Lepidoptera, there is sometimes a gliding component to
their flight.
•Flight occurs either as hovering, or as forward or backward motion

Why butterflies and moths are important?
• There are part of nature heritage • They have been studied for over 300
years.• Butterflies are used by advertisers
and illustrators as way of indicating that something that environmental
friendly.• Butterflies also often portrayed as the
essence of nature or even representing freedom, beauty and
peace.

Ecosystem Value
• Butterflies and moths have fascinating life-cycles that are used to teach
students about the natural world. • The transformation of an egg to

Educational Value
