三只山地飞蛾的铜版观察页

One original standalone natural-history illustration as a copperplate etching on warm paper, vertical 4:5: three different alpine moth species arranged around a sprig of mountain thyme, fine cross-hatched wings, copper-brown engraved lines and carefully observed antennae. Quiet scientific plate composition with generous margins and subtle plate impression, no labels, names, letters, numbers, logo, watermark, modern photo collage or grid.

竖幅铜版蚀刻自然志插画：暖纸上三只不同的高山飞蛾环绕一枝山百里香，翅膀以细密交叉排线刻画，触角形态各异。铜棕色刻线、轻微版压印和宽阔留白，像一张安静的观察页；没有名称、编号或现代拼贴。
