Gromphadorhini Posted March 4, 2020 Share Posted March 4, 2020 I have been engaged in Gromphadorhini species for quite some time and throughout the whole time, and I observe in all cultures without exception a whitish coating on the tergites of the male abdomen. I noticed that it appears only in mature males, who are very active and exhibit pronounced sexual behavior. Males that do not exhibit this behavior have no plaque. What do you think it could be?
