Subject: Which types of ants are edible to humans?

I have seen many documentary movies that show chimpanzees putting a twig 
into an ant nest. The ants climb on it and the chimpanzees then pull the 
twig and lick the ants. Since chimpanzees are biologically close to 
humans, one might ask if humans can do the same. Yet, in the area where I 
live, ants roam freely and I have not seen any animal that dares even to 
smell them. (I smelled one and it felt like a hot knife stuck in my nose. 
Not to talk about the taste.)Since no animal dares to eat them, I assume 
they are highly toxic. Are chimpanzees better suited than humans for the 
task? Which types are edible to humans, and which types have to be avoided 
even by the ant-eater?
