When the Mantis (Rear-horse) kneels, it sees an angel in the way, or hears the rustle of its wings. When it alights on your hand, you are about to make the acquaintance of a distinguished person; if it alights on your head, a great honor will shortly be conferred upon you. If it injures you in any way, which it does but seldom, you will lose a valued friend by calumny. Never kill a Mantis, as it bears charms against evil. From the great resemblance of many species of Mantis to the leaves of the trees upon which they feed, some travelers, who have observed them, have declared that they saw the leaves of trees become living creatures, and take flight. Madame Merian informs us of a similar opinion among the Indians of Surinam, who believed these insects grew like leaves upon the trees, and when they were mature, loosened themselves and crawled, or flew away. We find also in the works of Piso an account of insects becoming plants. Speaking of the Mantis, that author says: “Those little animals change into a green and tender plant, which is of two hands breadth. The feet are fixed into the ground first; from these, when necessary humidity is attracted, roots grow out, and strike into the ground; thus they change by degrees, and in a short time become a perfect plant. Sometimes only the lower part takes the nature and form of a plant, while the upper part remains as before, living and movable; after some time the animal is gradually converted into a plant. In this Nature seems to operate in a circle, by a continual retrograde motion.”[272]
