Is a ladybug that eats plants a herbivore?

Technically speaking, ladybugs that eat aphids are aphidophagous, and ladybirds that eat coccids are coccidophagous; which makes them carnivores. However, some ladybirds like the Mexican bean beetle are strict herbivores and others eat both pollen and aphids, making them omnivores. So the REAL answer is: BOTH (or all three plus more), depending on the species...
