三隻山地飛蛾的銅版觀察頁

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.

豎幅銅版蝕刻自然志插畫：暖紙上三隻不同的高山飛蛾環繞一枝山百里香，翅膀以細密交叉排線刻畫，觸角形態各異。銅棕色刻線、輕微版壓印和寬闊留白，像一張安靜的觀察頁；沒有名稱、編號或現代拼貼。
