7. Butterflies and Moths
1
You see an insect with colorful wings resting on a flower
2
Is it a butterfly or a moth?
If you see it during the day, It is probably a butterfly
3
Most moths fly only at night
A butterfly’s body is thin and smooth
4
A moth’s body is thick and furry
Butterflies hold their wings straight up
5
Moths spread their wings out flat
But butterflies and moths are alike in two (2) ways
6
Both have wings covered with colorful scales
Both have long, rolled-up tongues
7
They use their tongues to drink nectar from flowers
As they feed, they carry pollen from one flower to another
8
This helps seeds and fruit to grow
Female moths and butterflies lay eggs on leaves or stems
9
The eggs hatch into caterpillars
10
Vocabulary:
caterpillars
The wormlike stage of a butterfly or moth
The caterpillars most important job is to eat
11
Caterpillars feed mostly on leaves
In fact, a tree may die if caterpillars eat many of its leaves
12
Caterpillars that become moths change inside a cocoon of silk
13
Vocabulary:
cocoon
The silk covering that some caterpillars make before becoming
a moth
The silkworm moth makes its cocoon from one silk thread that is
1,000 yards long
14
People use this thread to make silk cloth
Most caterpillars that become butterflies do not make a cocoon
15
Instead the skin becomes a hard case
The caterpillar becomes a pupa
16
Vocabulary:
pupa
A stage in the life of a caterpillar when the skin gets hard
Inside the pupa, wings grow
17
Soon an adult butterfly comes out
