Abstract Three species of sawflies, along with their particular host plants, were examined for neutral sterols. Cholesterol was the predominant sterol in the sawfliesDolerus nitens (56.6%) andAneugmenus flavipes (73.0%), with lesser amounts of sitosterol, campesterol and desmosterol.Xiphydria maculata, however, contained unusually high levels (74.9%) of 7-dehydrocholesterol. Based on the sterol composition of their individual host plants, which contained primarily 28- and 29-carbon sterols, it is likely that all three sawfly species are capable of dealkylation of phytosterols.
