Adaptation of Instinct in a Trap-door Spider

Nature volume 63, page 466 (14 March 1901) | Download Citation



THE following extract from the Sydney Bulletin, January 12, sent to me by a correspondent in Western Australia, recounts an observation sufficiently interesting, I think, to be reprinted and put on permanent record in a scientific periodical:—“A friend of mine noticed near his camp a trap-door spider run in front of him and pop into its hole, pulling the ‘lid’ down as it disappeared. The lid seemed so neat and perfect a circle that the man stooped to examine it, and found, to his astonishment, that it was a six pence! There was nothing but silk thread covering the top of the coin, but underneath mud and silk thread were coated on and shaped convex (as usual). The coin had probably been swept out of the tent with rubbish.”
