The littoral Collembola Cryptopygus clavatus spends the summer submerged, grazing on algae under water, and the winter on dry land. The cuticles of Collembola are, in general, highly water repellent, often superhydrophobic; the cuticle of C. clavatus has, in contrast, been described as not water repellent. Wetting properties are closely tied to surface structuring, and previous studies of Collembola cuticles have used the pattern of cuticular granules to explain the superhydrophobic properties of these cuticles. The wetting properties of the cuticles of C. clavatus were measured on animals acclimated to summer and winter. A significant difference in wetting performance was observed. Animals acclimated to winter conditions showed superhydrophobic non-wetting properties. Animals acclimated to summer conditions were not superhydrophobic, water droplets readily adhered to their cuticles. This large change in wetting behavior of the cuticle could not be explained by changes in the cuticular surface structure, which were very limited. Instead, we suggest a change in the epicuticular wax layer could explain the differences.

Collembola Cryptopygus clavatus 角质层润湿特性的季节性变化 (Schött, 1893)

滨海弹跳虫 Cryptopygus clavatus 夏季潜入水中，在水下以藻类为食，冬季则在旱地上度过。弹尾虫的角质层通常具有高度防水性，​​通常是超疏水性的​​；相比之下，C. clavatus 的角质层被描述为不防水。润湿特性与表面结构密切相关，之前对弹尾虫角质层的研究使用角质层颗粒的模式来解释这些角质层的超疏水特性。在适应夏季和冬季的动物身上测量 C. clavatus 角质层的润湿特性。观察到润湿性能的显着差异。适应冬季条件的动物表现出超疏水的不润湿特性。适应夏季条件的动物不是超疏水的，水滴很容易附着在它们的角质层上。表皮润湿行为的这种巨大变化不能用表皮表面结构的变化来解释，这是非常有限的。相反，我们建议表皮蜡层的变化可以解释这些差异。
