There isn't a specific term for a chipmunk that eats seeds or fruit.

Here's why:

* Chipmunks are omnivores: They naturally eat a variety of foods, including seeds, fruit, nuts, insects, and even small animals.

* "Herbivore" would be incorrect, as they don't exclusively eat plants.

* "Granivore" would be partially accurate, as they do eat seeds, but not exclusively.

You could simply describe them as "chipmunks eating seeds" or "chipmunks feeding on fruit" to be specific about their diet in a given situation.
