I debate for a long time whether or not I should kill a huge ant. It doesn't move much. Perhaps it is the only member of its species left--apart from its five tiny young. Finally I kill the big ant with a spade but, by then, two or three of its young have escaped. I am afraid that when they grow up they will come back and revenge the death of their parent ant.I use the spade again to turn the beautiful sedge, soil, sand and water where the ants were living. I can see their tunnels and tombs. I search desperately for eggs but can't see any.
