In the feeling and protection of their genetic descendant, insects and spiders show off some zeal in analogies to reasoning and some sensitive examples of blind instinct. The case I present here is the digger wasps of genus Pepsis and tarantula spiders together with their opponent. An example is a non-familiar situation which the victim, though fully able to defend itself, gives up accidentally to its destruction. A lot of tarantula spiders reside in the tropics, but many species appears in the temperate zone and a little are common in southern U.S. Some types are large and have strong fangs with which they can inflict a deep wound. These spiders are not harmful to mankind and one can hold them in a gentle manner to avoid any kind of bite from them. It is only harmful on insects and small mammals like mice. For human, it is no worse than a hornet’s sting. In a Paris museum, is a tropical specimen which is said to have been living in confinement for 25 years. The male tarantula and matured ones as well does not have long life after it mates with its female tarantula, but the female tarantula will leave long and mate with several male tarantulas. Matured male tarantulas wander about after dark in search of female tarantulas and occasionally go into houses. Tarantulas customarily live in deep cylindrical burrows. Laboratory experiments have proven that, tarantulas can differentiate three types of touch: pressure against the body wall, stroking of the body hair and riffling of certain very fine hairs on the legs called trichobothria. When one uses the tip of a sharpen wood to compress the body it makes the tarantula spider to move slowly a little while. The tarantula may react when the compressing continue for some time and can hold the object that is threatening it. Whiles spiders and especially hairy ones have an extra delicate sense of touch. These three tactile responses are so different from one another that there is no point in...
