White-Stemmed Acacia Moth

Often called the Large Anthelid Moth, this is a true titan of the Australian night. With a wingspan that can rival a small bird, seeing one resting on a porch light can be a startling experience for the uninitiated. While the adult is a gentle, fuzzy giant, its "teenage" caterpillar stage is famous for being one of the prickliest characters in the bush.

🔍 How to Identify

• 🦋 Massive Wingspan: This is one of Australia's largest moths; females can reach a staggering wingspan of nearly 15 centimeters (6 inches).
• 🎨 Earth-Toned Camouflage: The wings are decorated with complex patterns of chocolate brown, slate grey, and tan, featuring distinct wavy lines that mimic the texture of tree bark.
• 📐 Scalloped Edges: The trailing edges of the wings have a unique, "toothed" or scalloped appearance rather than being perfectly smooth.

🌲 Habitat & Ecology

• 🌳 Wattle & Gum Specialist: As their name suggests, they are most at home in Eucalyptus forests and woodlands where Acacia (Wattle) trees grow, providing the perfect nursery for their larvae.
• 💡 The Light Trap: Being strictly nocturnal, they are frequently found in suburban backyards, clinging to window screens or walls near outdoor lights where they wait for dawn.
• 🏗️ Fortified Cocoons: They don't just spin silk; they build incredibly tough, double-walled cocoons often hidden under loose bark or in leaf litter.

⚠️ Safety & Toxicity

• 🚫 Handle with Caution: While the adult moth is physically harmless (it has no stinger and doesn't bite), it should be handled gently to avoid damaging its delicate scales.
• 🐛 The "Sting" of the Larva: The caterpillars are covered in stiff, brittle hairs that break off in the skin. Touching one can cause a painful, itchy rash (urticaria) that lasts for days. Even the cocoons are "booby-trapped" with these hairs!

✨ Fun Fact

The caterpillar of the Chelepteryx chalepteryx is so well-protected that it doesn't even bother to hide; it grows to a massive 10-12cm in length and marches boldly across tree trunks, confident that its "coat of needles" will deter any hungry birds.
