The genus Eurydema has had an unusually high level of confusion concerning the various contained species. The main source of confusion stems from the plethora of varieties described for several of the more common species. Furthermore, early workers confused several of the more common forms. For example, most early references to ornata should actually apply to ventralis, most early references to festiva (a junior synonym of ornata) should be referred to dominulus, and most early references to dominulus should be referred to fieberi. Finally, the multitude of varietal names (also called forms or aberrations) are mostly nothing more than colour forms, and should not be given subspecies status.
