Life cycle of a grasshopper demonstrating incomplete metamorphosis.

You’re working on Worksheet 2: Life Cycle of Selected Animals (Complete and Incomplete Metamorphosis). Let’s solve both parts step by step.

## ✔ PART A: Supply the missing stages in the life cycle

Left Image (Butterfly — Complete Metamorphosis)

This is a classic example of complete metamorphosis, which has 4 stages:
Egg → Larva → Pupa → Adult

Looking at the diagram:

- Stage 1 shows an adult butterfly laying eggs on a leaf → this is the adult stage.
- Stage 2 shows a caterpillar eating leaves → this is the larva stage.
- Stage 3 shows a chrysalis (pupa) hanging from a branch → this is the pupa stage.
- The egg stage is not labeled but is implied to come before the larva.

So, the labels should be:

> 1 = Adult
> 2 = Larva
> 3 = Pupa

*(Note: The egg stage is usually shown as the first stage, but since it’s not numbered here, we label what’s shown.)*

Right Image (Grasshopper — Incomplete Metamorphosis)

This is an example of incomplete metamorphosis, which has 3 stages:
Egg → Nymph → Adult

Looking at the diagram:

- Stage 4 is an oval-shaped egg.
- Stage 5 is a small grasshopper with no wings — this is the nymph stage (looks like a miniature adult).
- Stage 6 is the full-grown winged grasshopper — this is the adult stage.

So, the labels should be:

> 4 = Egg
> 5 = Nymph
> 6 = Adult

## ✔ PART B: Classify animals as Complete or Incomplete Metamorphosis

Let’s go through each animal:

🦋 Butterfly → Complete Metamorphosis

- Stages: Egg → Caterpillar (larva) → Chrysalis (pupa) → Adult butterfly

🐜 Grasshopper → Incomplete Metamorphosis

- Stages: Egg → Nymph → Adult (no pupa stage)

🐞 Ladybug → Complete Metamorphosis

- Egg → Larva → Pupa → Adult (ladybugs are beetles — all beetles have complete metamorphosis)

🐝 House Fly → Complete Metamorphosis

- Egg → Maggot (larva) → Pupa → Adult fly

🦟 Mosquito → Complete Metamorphosis

- Egg → Larva (wriggler) → Pupa → Adult mosquito

🐉 Dragonfly → Incomplete Metamorphosis

- Egg → Nymph (aquatic) → Adult (no pupal stage — nymph molts directly into adult)

## ✍️ Final Answers for Part B Table:

| Complete Metamorphosis | Incomplete Metamorphosis |
|------------------------------|---------------------------|
| Butterfly | Grasshopper |
| Ladybug | Dragonfly |
| House Fly | |
| Mosquito | |

*(Note: “Ladybug” was written as “lousely” in your image — that’s likely a typo for “ladybug”)*

## 🧠 Summary of Key Concepts:

- Complete Metamorphosis = 4 stages: Egg → Larva → Pupa → Adult
→ Dramatic change in body form; larva looks nothing like adult.
→ Examples: Butterflies, beetles, flies, mosquitoes, bees.

- Incomplete Metamorphosis = 3 stages: Egg → Nymph → Adult
→ Nymph resembles adult but smaller, no wings, may live in different habitat.
→ Examples: Grasshoppers, crickets, dragonflies, cockroaches.
