| 摘 要： | Twenty-nine species (24 genera, 6 families) of butterflies typical and common in northeast China were selected to make qualitative and quantitative studies on the pattern, hydrophobicity and hydrophobicity mechanism by means of scanning electron microscopy and contact angle measuring system. The scale surface is composed of submicro-class vertical gibbosities and horizontal links. The distance of scale is 48—91 μm, length 65—150 μm, and width 35—70 μm. The distance of submicro-class vertical gib-bosities on scale is 1.06—2.74 μm, height 200—900 nm, and width 200—840 nm. The better hydropho-bicity on the surface of butterfly wing (static contact angle 136.3°—156.6°) is contributed to the co-effects of micro-class scale and submicro-class vertical gibbosities on the wing surface. The Cassie equation was revised, and new mathematical models and equations were established.

| Abstract: | Twenty-nine species (24 genera, 6 families) of butterflies typical and common in northeast China were selected to make qualitative
and quantitative studies on the pattern, hydrophobicity and hydrophobicity mechanism by means of scanning electron microscopy
and contact angle measuring system. The scale surface is composed of submicro-class vertical gibbosities and horizontal links.
The distance of scale is 48–91 μm, length 65–150 μm, and width 35–70 μm. The distance of submicro-class vertical gibbosities
on scale is 1.06–2.74 μm, height 200–900 nm, and width 200–840 nm. The better hydrophobicity on the surface of butterfly wing
(static contact angle 136.3°–156.6°) is contributed to the co-effects of micro-class scale and submicro-class vertical gibbosities
on the wing surface. The Cassie equation was revised, and new mathematical models and equations were established.
