Since the main defence of every ant colony is a recognition system based on smell, some invading queens fight with workers of the host species outside the nest, kill them, take their odour sacs and obtain a chemical disguise before entering the host nest.
The animal world fascinates me for two reasons. Their talents and abilities far exceed ours. They are so similar to humans in the way they feel emotion and handle problems.
And no species are more humanlike than ants.
None of us like working. We would all like to be waited on hand and foot. Many nations go to war for slaves – the Roman Empire was built on them. The Americans picked them up from Africa. The entire middle class upwards of India exists because someone else who needs the money comes in to cook, clean and look after the children.
