_Mrs. B There is none, how large soever, that they will not attack and devour. The blue fly, the bee, the wasp, and the hornet, are their constant prey; and even your favourite butterfly is often caught, and treated without mercy. Their appetite seems to know no bounds; and they have been seen to devour three times their own size, in the space of a single hour. "Oh, the greedy creatures; I cannot forgive them for destroying the pretty butterflies," said Ferdinand: "to wasps and hornets they are perfectly welcome. Are they produced from eggs, like other insects, pray, mamma?" "Yes, my dear: the female deposits her eggs in the water, where they remain some time, apparently without life or motion. The form they first assume, is that of a worm with six legs, much resembling the dragon-fly in its winged state, the wings being as yet concealed within a sheath peculiar to this animal." "What do they feed upon in this state, pray, mamma?" enquired Louisa. "Upon the soft mud and glutinous earthy substances that are found at the bottom," replied her mother. "Pray, mamma, how long do they continue in their reptile state?" said Emily. "For a whole year, my dear," returned her mother. "When they parepare to change to their flying state, they move out of the water to a dry place; such as into grass, to pieces of wood, stone, or any thing else they may meet with. There they firmly fix their sharp claws, and, for a short time, continue quite immovable. It has been observed, that the skin first opens on the head and back, and out of this aperture they exhibit their real head and eyes, and at length their six legs; whilst the hollow and empty skin remains firmly fixed in its place. After this the creature creeps forward by degrees; drawing, first its wings, and then its body, out of the skin; it then sits at rest for some time. The wings, which were moist and folded together, now begin to expand. The body is likewise insensibly extended, until all the limbs have attained their proper size. The insect cannot at first make use of its new wings, and is, therefore, obliged to remain stationary until its limbs are dried by the air. It soon, however, begins to enter upon a more noble life than it had before led at the bottom of the brook; and from creeping slowly, and living accidentally, it now wings the air, adorning the fields with beauty, and expanding the most lively colours to the sun." "Well, my pretty fly," said Ferdinand, "you have afforded me much amusement, and now I will release you from your captivity." So saying, he opened his handkerchief, and gave his prisoner liberty. In a few minutes they reached home, highly pleased with their morning's ramble. CONVERSATON IX.
