# # 🌿 Introduction

# # 🦋 How the Butterfly Life Cycle Works
Understanding the life cycle is the key to success.
1. **Egg** – Laid on specific host plants
2. **Caterpillar** – Eats leaves (this is normal!)
3. **Chrysalis** – Transformation stage
4. **Butterfly** – Feeds on nectar and lays eggs
👉 **No host plants = no caterpillars = no butterflies**

# # 🌱 Host Plants (For Caterpillars)
These plants are essential. Expect some leaf damage – that means you’re doing it right.
# # # Common Illawarra Host Plants
* **Citrus Trees** – Orchard Swallowtail
* **Native Violet (Viola hederacea)** – Meadow Argus
* **Native Grasses (Poa, Themeda)** – Skippers
* **Senna species** – Grass Yellow butterflies
* **Pea Flowers (native & ornamental)** – Common Blues
* **Milkweed (Asclepias species)** – Monarch Butterfly
📝 *Important note: Milkweed is not native. Grow responsibly in pots or controlled areas and never allow it to spread into bushland.*
📝 *Tip: Always plant host plants in clusters so butterflies can find them easily.*

# # ☀️ Garden Design & Placement
Butterflies are sun-lovers but hate strong wind.
✔ Morning sun preferred
✔ Shelter from southerly & westerly winds
✔ Group plants together
✔ Avoid dark, cold corners
# # # Water for Butterflies
Use a **shallow dish** with sand or stones and keep it topped up.

# # 🚫 What to Avoid
Chemical use is the biggest butterfly killer.
❌ Pesticides & insecticides
❌ “Eco” sprays during caterpillar season
❌ Over-tidying the garden

🛑 If you kill caterpillars, you kill future butterflies.
