Order Lepidoptera - Butterflies and Moths

• Proboscis (feeding)
• 2 pairs wings
• Complete metamorphosis

(egg-larva-pupa-adult)

• Compound eye and ocelli
• Spiracle – breathing

(oxygen in; carbon dioxide out)

• Tiny scales on wings that overlap

(Lepido = scales; ptera = wing)

The Painted Lady

Painted Lady

Scales on wings - flatten hairs

Eterusia repleta

Luna moth

Male Monarch - “dots”

Milkweed is the “host” plant of Monarch

Tropical Milkweed

Silkworm - the larva stage of Bombyx mori

Making a cocoon

See all the stages

chrysalis is the hardened body of a butterfly pupa

cocoon is an external structure constructed by larvae for protection

Activity

• Put the life cycle of the luna moth and the monarch butterfly in order.

​

• Then create a Venn Diagram to compare
• What is the same?
• What is different?

Butterflies

Moths
