What do golden beetles eat?

Yes, some green beetles eat ants even though no, others do not. The six-spotted tiger beetle (Cicindela sexguttata) includes ants among a diet of aphids, caterpillars, earwigs, field crickets, flies, fungus gnats, grasshoppers, katydids, lacewings, mosquitoes, sawflies, snow fleas, Spiders, springtails and termites. Green June (Cotinis nitida) and Japanese (Popillia japonica) beetles serve as recognizable examples of green coleopterans that are plant-eating herbivores instead of flesh-eating carnivores.
