Are Callistephus and Epacris native to the same area of the world ?
Epacris Epacris is a genus of about 35–40 species of flowering plants in the family Ericaceae. It was formerly treated in a closely related but separate family Epacridaceae, but the various genera within Epacridaceae including "Epacris" have been revised in their relationships to each other and brought under the common umbrella of the Ericaceae. The genus "Epacris" is native to eastern and southeastern Australia (southeast Queensland south to Tasmania and west to southeast South Australia), New Caledonia and New Zealand. The species are known as heaths or Australian heaths.
Altica Altica (New Latin from Greek ἁλτικός , "haltikós", "jumper" or "jumping") is a large genus of flea beetles in the subfamily Galerucinae, with about 300 species, distributed nearly worldwide. The genus is best represented in the Neotropic region, well represented in the Nearctic and Palearctic, but occurs also in the Afrotropic, Indomalaya and Australasia. The species are similar to each other, small metallic blue-green-bronze beetles, often distinguished from each other only by the aedeagus. The species of "Altica", both as larvae and as adults, are phytophagous, feeding on plant foliage of various food plant taxa, specific for each "Altica" species. Onagraceae and Rosaceae (mainly "Rubus") are the dominant host plant families for Holarctic species. The adult "Altica" beetles are able to jump away when approached.
