Gorillas aren't vegetarian.  They eat so many of those little
insects (both with their fruit and on the side) that you can't
rightfully call the diet vegetarian.  Bugs come from the fauna realm,
not the flora.  Sorry, but insects on the menu is not a vegetarian
diet. The insects may be little, but primates eat an awful lot of
them. But you are right, gorillas do demonstrate this fact.
