. The wonder of life. Biology; Natural history; Zoology. 34 THE WONDER OF LIFE Let us take an instance. From a pale emerald-green nest, sent from the Gold Coast to the Zoological Society in London, there emerged a crowd of young Mantids, about four milli- metres in length, which exhibited a curious mimicry. ' When crawHng about the case they looked exactly like a crowd of busy ants, their rapid darts and pauses recalhng irresistibly the busy method of progression so characteristic of these Hymenoptera '. Now, there is nothing more pro- fitable for an iimocent httle insect than to be hke an ant, for ants have a very bad reputation, or what corresponds in the animal world to a reputation. But the interesting point which was noticed by Mr. R. I. Pocock, the Superin- tendent of the Gardens, was this, that it was only when they were moving about that they resembled ants. When they settled down they were seen in their true colours—as Mantises, 'raising the fore part of the body and head, folding up their fore-legs, and every now and then swaying gently from side to side as if rocked by the wind. While thus employed they were seen to be procrypti- cally coloured '. That is to say, they were inconspicuous. This is obviously a very interesting case ; when the httle creatures were resting they were hidden, and when they were poking about they were like ants! Without observations and experiments in their natural surroundings no naturahst could assert that the Fig. 12.—Spider, Synemo- young Mantises are saved from syna formica, like an . ant.
