Argentine ants are the ones I know of that do aphid and scale farming around here. They are really aggressive little buggers and are known to have caused the extinction of a species of butterfly whose larvae were previously tended by native ants but the Argentine guys kill all the native ants. The problem with them is that there was a small genetic stock that took root here so it's just one big megacolony. In Argentina they fight among their own neighboring colonies and keep balanced that way but here they just wipe everything else out. david b. williams wrote: >Greetings.
