Generating a Butterfly Image with Selective Iridescence AI Image Prompt

Comparison of the front and back of a mounted specimen of a male Atrophaneura alcinous spring form. The information in this illustration shows that the structural color on the left and the matte brown on the right are the same butterfly. When you write 'iridescent' to the AI, everything shines. The job of the prompt is to specify 'this part shines, this part does not shine'.

This prompt is designed to address a common issue in AI image generation where specifying 'iridescent' makes the entire subject glow. The goal is to generate an image of a butterfly (specifically a male *Atrophaneura alcinous* spring form) that accurately depicts selective structural color (iridescence) on the left wing and a matte brown color on the right wing, requiring precise control over light and texture.
