How ?? From fossil (Archaeolepis Mane) From Jurassic period (190 million years ago)
2 other sets of Jurassic Lepidopteran fossils have been found 13 sets from the Cretaceous period
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.

General Feature For Both Butterfly And Moth
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 adult 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 mode
Moth : ~ does not eat anything(use nutrient consumed at larval stage) ~ fruit
~ tree sap
~ rotting fruit
~ 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 moth
Are they migrate ?
W hat 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.
Butterflies and moths are indicators of a healthy environment and healthy ecosystem.
Provides a wide range of environmental benefits which includes pollination and natural pest control.
They are an important element of the food chain and are prey for birds, bats and insectivorous animals.
Butterflies and moths have fascinating life-cycles that are used to teach students about the natural world.
The transformation of an egg to caterpillar and chrysalis is one of the wonders of nature.
Intricating the wing patterns and iridescence and as examples of insect migration
Every butterflies and moths has developed its own type of chemicals to deter predators and parasites, finding a mate, overcome the chemical defense of its host plant.
Each of this chemicals is potentially value and could be exploited economically.
Eg: powerful antibiotics has been found in the Meadow Brown.
