There are ants that farm and "milk" aphids https://www.mcgill.ca/oss/article/did-you-know/farmer-ants-a...
Ants farm aphids and another species of ant farms fungus.
Parasites are ubiquitous in nature and they range from the infamous cuckoo who lays eggs in other birds’ nests to tiny worms that infest the eyes of children to the horrifying tarantula hawk wasp that paralyses a spider and leads it to a burrow and then lays an egg which soon hatches and devours the still-living spider from the inside out!
It makes me wonder if humans are the only animals who "farm" other animals in some way (not on the same scale as humans do of course).
At the same time, it makes me wonder, "is being a parasitic animal socially better or worse than animals who farm fellow animals" ;).
