Elegant Swallowtail on Lavender in Sunny Field

Photorealistic macro scene of an elegant swallowtail butterfly perched on a vibrant lavender flower in a sunlit meadow. The butterfly resembles Papilio machaon, with bold yellow and black wings and long hindwing tails, wings partly open to reveal intricate patterns and a subtle metallic sheen. The lavender spike is in sharp focus, with dew-like droplets catching sunlight on purple petals and green stems. A shallow depth of field renders the lavender field and distant trees in a soft bokeh, with warm golden-hour sun rays filtering through a clear blue sky. The composition centers on the butterfly and the lavender, balanced by the lines of the stems. The overall mood is bright, tranquil, and summery; ultra-high detail, 8K, photorealistic, macro lens.
