Page 2: Invertebrates

You see an insect with colorful wings resting on a flower

2

Is it a butterfly or a moth?

Page 3: Invertebrates

If you see it during the day, It is probably a butterfly

3

Most moths fly only at night

Page 4: Invertebrates

A butterfly’s body is thin and smooth

4

A moth’s body is thick and furry

Page 5: Invertebrates

Butterflies hold their wings straight up

5

Moths spread their wings out flat

Page 6: Invertebrates

But butterflies and moths are alike in two (2) ways

6

Both have wings covered with colorful scales

Page 7: Invertebrates

Both have long, rolled-up tongues

7

They use their tongues to drink nectar from flowers

Page 8: Invertebrates

As they feed, they carry pollen from one flower to another

8

This helps seeds and fruit to grow

Page 9: Invertebrates

Female moths and butterflies lay eggs on leaves or stems

9

The eggs hatch into caterpillars

Page 10: Invertebrates

Vocabulary:

caterpillars

The wormlike stage of a butterfly or moth

Page 11: Invertebrates

The caterpillars most important job is to eat

11

Caterpillars feed mostly on leaves

Page 12: Invertebrates

In fact, a tree may die if caterpillars eat many of its leaves

12

Page 13: Invertebrates

Caterpillars that become moths change inside a cocoon of silk

13

Vocabulary:

cocoon

The silk covering that some caterpillars make before becoming

a moth

Page 14: Invertebrates

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

Page 15: Invertebrates

Most caterpillars that become butterflies do not make a cocoon

15

Instead the skin becomes a hard case

Page 16: Invertebrates

The caterpillar becomes a pupa

16

Vocabulary:

pupa

A stage in the life of a caterpillar when the skin gets hard

Page 17: Invertebrates

Inside the pupa, wings grow

17

Soon an adult butterfly comes out
