We have a variety of ants here. Some are quite large and others very tiny. Most are black but some are red. We also have what we call fire ants. They can cause quite some pain. I had a chicken that was eating some fire ants until the sting set in. Then it began shaking its head and ran away from the ants, never to touch them again. There are also fire ants at one of the popular dog-walking parks. When those climb onto a dog, the dog begins scratching and jumping all over the place. I have luckily never experienced the pain of fire ants myself, so cannot know exactly how bad the pain is.

If you look closely at the larger aphids, you will see 2 "pipes" sticking out of the back end of the aphid. That's where the fluid comes out. Ants don't have breasts (at least not in the sense you are thinking). The ant uses its antenna to rub the aphid on it's back. Then a drop of juice comes out a pipe and onto a leaf. The ant takes the juice from the leaf. Hopefully that paints a more accurate picture for you.

Fire ants sounds really painful and scary. I googled for their picture, it showed the one like in Ant-man movie :P

Yeah now I understand how the milking happens, thanks for explaining so well :):)

You are most welcome.
