For this pest of Africa, the southern winds have provided means of flight as well, for as the breeze bears them along, they extend their arms and ply them like so many oars in their flight; the same Apollodorus, however, asserts that there are some which really have wings.[96] The Psylli, who for their own profit have been in the habit of importing the poisons of other lands among us, and have thus filled Italy with the pests which belong to other regions, have made attempts to import the flying scorpion as well, but it has been found that it cannot live further north than the latitude of Sicily. However, they[97] are sometimes to be seen in Italy, but are quite harmless there; they are found, also, in many other places, the vicinity of Pharos, in Egypt, for instance. In Scythia, the scorpion is able to kill the swine even with its sting, an animal which, in general, is proof against poisons of this kind in a remarkable degree. When stung, those swine which are black die more speedily than others, and more particularly if they happen to throw themselves into the water. When a person has been stung, it is generally supposed that he may be cured by drinking the ashes of the scorpion[98] mixed with wine. It is the belief also that there is nothing more baneful to the scorpion and the stellio,[99] than to dip them in oil. This last animal is also dangerous to all other creatures, except those which, like itself, are destitute of blood: in figure it strongly resembles the common lizard. For the most part, also, the scorpion does no injury to any animal which is bloodless. Some writers, too, are of opinion that the scorpion devours its offspring, and that the one among the young which is the most adroit avails itself of its sole mode of escape, by placing itself on the back of the mother, and thus finding a place where it is in safety from the tail and the sting. The one that thus escapes, they say, becomes the avenger of the rest, and at last, taking advantage of its elevated position, puts its parents to death. The scorpion produces eleven at a birth.
