The temperature-dependent structural changes of the cuticular hydrocarbons covering the forewing of an American cockroach were able to be followed, which showed that the majority of the hydrocarbons were in a liquid state even far below the critical temperature of water transpiration through the body surface. The results clearly demonstrated that synchrotron radiation X-ray scattering has the potential to obtain the detailed information about the intact lipid structure and physical properties on insect body surfaces.American Chemical SocietyJournal Articlehttp://hdl.handle.net/2115/811691948-7185Journal of physical chemistry letters127196919722021-02-25enginfo:doi/10.1021/acs.jpclett.0c03776none
