Bilberry Emerald

Often called the Common Emerald, Jodis putata is a delicate, mint-green treasure of the moth world. Resembling a fresh spring leaf, it is a quintessential "friend" to the nature lover and a highlight for any night-time observer. Its subtle beauty is a masterclass in camouflage, allowing it to vanish against the foliage of the heathlands it calls home.

🔍 How to Identify

• 🦋 Minty Hue: The wings feature a soft, translucent green color that can range from a pale aqua to a seafoam tint.
• 〰️ White Cross-lines: Look for two distinct, white, jagged lines (medial lines) that "zig-zag" across both the forewings and hindwings.
• 📐 Scalloped Edges: The wing margins are not perfectly smooth; they have a slightly wavy or scalloped appearance, mimicking the edge of a leaf.

🌲 Habitat & Ecology

• 🫐 Bilberry Specialist: This moth is deeply tied to its food source. The caterpillars (larvae) are "loopers" that feed primarily on Bilberry (Vaccinium myrtillus) and occasionally Heather.
• 🌙 Nocturnal Nature: While they fly mostly at night, they are easily disturbed from low-growing shrubs during the day. If you kick up a small green "butterfly" while hiking through a moor, it is likely this moth.
• 🍃 Invisible Larvae: The caterpillars are experts at mimicry, stretching their bodies out to look exactly like the twigs of the plants they eat, making them nearly invisible to birds.

⚠️ Safety & Toxicity

• ✅ Completely Harmless: This moth is a gentle visitor. It lacks any stinging apparatus, biting mandibles, or chemical irritants.
• 🐾 Pet & Child Safe: There are no known toxins associated with this species. It is perfectly safe if it accidentally flutters into your home or is investigated by a curious pet.

✨ Fun Fact

The "Emerald" color is famously fleeting! Unlike many other insects, the green pigment in Jodis putata is chemically unstable. As the moth gets older, or if a specimen is kept in a collection, the vibrant green slowly fades into a dull, creamy white.
