Abstract Hydroxylated anthraquinones have been found to accumulate in different developmental stages of the chrysomelid beetle Trirhabda geminata. Eggs, larvae and adults were analyzed by HPLC and GC-MS. Each developmental stage analyzed contained 1,8-dihydroxy-3-methyl-anthraquinone (chrysophanol) and 1,8-dihydroxyanthraquinone (chrysazin). No anthraquinones were detected in the faeces of T. geminata. The level of stored anthraqui­ nones did not change during starvation. In the host plant of this specialist herbivore, the brittlebush Encelia farinosa (Asteraceae), anthraquinones were not detected. Possible biolog­ical functions of anthraquinones stored in T. geminata are discussed.
