Generating a Butterfly Image with Selective Iridescence

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.
