Differences in Nanostructure and Hydrophobicity of Cicada (Cryptotympana atrata) Forewing Surface with the Distribution of Precipitation

Figure 5

Correlation of protrusion diameter (a–c) with the monthly precipitation of locations and the year the samples of cicada Cryptotympana atrata were collected. (a–c) The diameter of nanostructure parameters has a significant correlation with the precipitation in June, November, and annual rainfall. (d–i) The spacing shows significant correlation with the precipitation in February, June, September, November, December, and annual rainfall. (j) The contact angle (CA) shows significant correlation with the precipitation in July. Precipitation data were collected from the China Meteorological data.
