In Batulawang, Indonesia, a single image depicts a dark-winged butterfly at rest on an open human hand. The butterfly, observed with its wings spread flat, exhibits a predominantly dark brown or black coloration, accented by a distinct blue iridescence along its central body and potentially some wing veins, under a strong blue light source or filter. Its two antennae are visible, extending forward. The human hand, positioned palm-up with fingers extended, serves as the resting surface for the butterfly, occupying the lower half of the frame. The background is out of focus, appearing as an undifferentiated dark blue field. The entire scene is rendered with a pervasive blue monochromatic cast, affecting all visible elements.
