Etymology: Folivorous comes from Latin "folium," meaning "leaf," joined to "-vorous," from Latin "vorare," "to devour" (the same root that gives English "voracious"). The combination is a modern scientific coinage, built from classical parts rather than used by ancient writers, and it was formed for zoologists describing animals whose diets are mostly foliage, such as koalas, sloths, and colobus monkeys. The "-vorous" element is the more productive of the two. It appears in carnivorous (flesh), herbivorous (plants in general), and insectivorous (insects), so folivorous narrows the category to leaves specifically. The pattern follows the same logic as frugivorous (fruit) and granivorous (seeds), which were likewise assembled from Latin roots in the 1800s.

Synonyms: leaf-eating
