The YELLOW-TAIL MOTH. The _Caterpillar_ feeds on _Elder_, _Oak_, _Black Thorn_, _&c._ upon all which Growths you may find them at the End of _May_. It changes to a _Chrysalis_, within a Spinning, at the Beginning of _June_, and the _Moth_ comes forth at the End of the same Month. They may be found sticking against the Barks of the Trees in Parks, and other Places, and also flying in the Evening. They lay Eggs of a pale Colour, and cover them with a woolly Substance. The _Caterpillars_ are hatch’d in _August_, and will feed on _Black Thorn_ till the End of _October_; at which Time they spin themselves little Cases, and remain in them till the Spring following.

The _Caterpillar_ feeds on _Rose_ Trees, Fruit-trees, and Shrubs; becomes a _Chrysalis_ within the Earth in _October_, and in _May_ following the _Moth_ appears, and may be found sticking against Pales, Walls, Trees, _&c._ Their Eggs are very small, and of a fine green Colour, and the _Caterpillars_ are common in Gardens and other Places. It is observed, that the Protuberance on the Back of the _Caterpillar_ is of a fleshy Substance, with Hair growing out of it. See _Albin_, P. 86. _Rosel_, Cl. 2. Tab. 7. _Reaumur_, Pl. 42. Pag. 602. The most double Sweet Briar Rose. _Rosa sylvestris, sive Eglanteria, flore pleno._ L. 1. CH. 1. V. CL. 3. S. _b._ 5. The WILD PINE-TREE LAPPIT-MOTH. Mr. _Rosel_ informs us, That the _Caterpillars_ of this curious Fly feed on the _Pinus sylvestris_, or WILD PINE: That they are full fed in the Month of _June_, at which Time they change to _Chrysalis_, within such a Spinning as is represented in the Plate; and, after lying in that State three Weeks the _Moths_ appear. About the Middle of _September_, 1748, I took one of these _Caterpillars_ upon a _White Thorn_ Bush, near _Richmond_ Park; which is still alive this 20th Day of _January_ 1748-9, though it has eat nothing, that I know of, since it has been in my Custody. It remains stretched out, in the Manner of the _Lappit-Caterpillar_ represented at the Letter _a_ of the first Plate of this Section; and I do not think it will begin to feed until there are Buds of _Black_ or _White Thorn_ to give it. This is the only _Caterpillar_ of the Kind that I have known taken in _England_.—For the Drawings exhibited in my Plate, I am obliged to Mr. _Rosel_. See _Rosel_, Cl. 2. Tab. 59.
