The WHITE-SATIN MOTH. Its _Caterpillar_ feeds on the _White Poplar_, as also on _Willow_; changes to a _hairy Chrysalis_, within the Leaves spun together, in _June_; lies in that State about twenty Days, and then the _Moth_ flies abroad. You may take these Flies by shaking the Boughs of the Trees they feed on. Their Eggs, when first laid, are of a pale green Colour, which they cover with a Substance looking like Leaf-silver. They continue about one Month in the Egg-state, and the _Caterpillars_ live all Winter. See _Lister_ on _Godart_. P. 84. N. 87. _Rosel_, Cl. 2, Tab. 9. _Reaumur_, Pl. 34. Pag. 534. Vol. 1.

The _Caterpillars_ are very common, and feed on most Kind of Herbage, especially _Black Thorn_, _White Thorn_, _&c._ about the Middle of _June_ they change to the _Chrysalis_ within a Case, which they spin, and cover with a fine Dust of the Colour of Brimstone. In this State they remain for about one Month; then the _Moth_ appears, and lays her Eggs, in a spiral Order, round the young Twigs of such Trees as are proper Food for the infant _Caterpillars_. They hatch in the Spring, and keep together in a Web while young. As these _Caterpillars_ are destructive in Gardens to Fruit-trees, _&c._ its adviseable to destroy them. See _Godartius_, P. 1.
