The major compounds are tolu- quinone and 2-methoxy-3-methylbenzoquinone, ac- companied by the minor components, 2,3-dimethoxy- benzoquinone and toluhydroquinone. Because of the large size and the geographic separation of the test animals a common defensive strategy of tropi- cal, large millipedes against predation by vertebrates is assumed.1 aDeml, R.1 aHuth, Angela  uhttps://scarabnet.myspecies.info/benzoquinones-and-hydroquinones-defensive-secretions-tropical-millipedes
