Many of the _Moth-Kind_ place their _Chrysalis_ in the Earth, about an Inch or two deep, surrounding it with a Case of Earth lined with a glutenous Matter, that no Wet can penetrate: And what is very surprizing, notwithstanding the extreme Delicacy and Tenderness of the _Fly_ when first bred, be the Ground never so hard, it makes its way thorough it without ruffling a single Feather. Few, if any, of the _Butterfly-Kind_ form a Case or Spinning, except what fastens the Tail and Body of the _Chrysalis_. Some hang perpendicularly downwards, and others in an horizontal Position, being fastened by the Tail, with a Thread round the Back and on each Side. Some are secured within the Leaves spun together; others are hid in the Hollows and Barks of Trees; and others again under the Copings of Walls, in Houses, Sheds, _&c._ Of the FLY. After the _Chrysalis_ has remained its due Time, the _Fly_ bursts the Shell wherein it was contained, and comes out formed perfectly in every Part, except the Wings, which then appear too small to cover its Body. In this naked Condition it crawls up to some convenient Place, where its Wings may hang down without any Hindrance: And when thus disposed, the Wings begin to expand themselves so much, that in the Space of half an Hour, the Wings (of _Butterflies_) are stretched commonly to their full Size; nay, even those of the largest _Moths_ seldom require above an Hour’s Time. At first they are flabby, like wet Paper, but soon afterwards they become stiff, and capable of supporting them in their Airy Flights, _&c._ In this _Fly_ State their first Care seems to be the Propagation of their Species, for some of them will copulate immediately if they can find a Mate; to seek which the Male _Butterfly_ takes Wing, as soon as his Wings are in a proper Condition: But few _Moths_, whether bred in the Night Time or in the Day, ever offer to fly till the Night after their Birth, when they go in Search of the Females. The Females (especially of the _Moth_ Kinds) seldom, if ever, take Wing till they have been cocked: they often continue in Conjunction twelve Hours and more, after which the Female lays her Eggs, flies about for a Time, and then dies.—The Females of some Kinds are without Wings. The Males (of some Species) have a surprizing Quickness and Distinction in their Sense of Smelling, exceeding that of the Blood-Hound, or any other Creature yet known; for if a Female be concealed in a Box, and there are any Males within half a Mile or more, they will fly directly to the Place, and hover round it. By this Means a Dozen Male _Egger-Moths_ have been taken in an Hour’s Time, and that at about Twelve o’Clock at Noon, as may be seen in the Account of the _Egger-Moth_.
