- Work on definition and scope (do we want this to be about primary consumers or just plant eating animals?)
- Dentition of herbivores
- Add section on herbivore impacts on plants (the short term impact, not the long term evolutionary pressure they create)
- Introduced herbivores
- Mutualism vs. herbivory - pollination and seed dispersal, and how they evolved.
- Add illustration of modes of herbivory (leaf eating, nectar feeding, root feeding, bark, stem, flower, seed, phloem feeding, leaf mining, gall forming etc.) (especially insect).
- Agricultural use
