The _Caterpillar_ feeds on _Oak-Leaves_, becomes a _Chrysalis_ at the Beginning of _June_, and in a Month after the _Fly_ appears. This _Butterfly_ is not so easily taken as some others, for when it is not feeding it usually settles high. I have taken the greatest Numbers early in a Morning, when I have found them feeding on the Blossoms of the _Blackberry_. See _Albin_, P. 57. _Rosel_, Cl. 2. Tab. 9. The Oak-Tree. _Quercus._ L. 3. CH. 2. II. CL. 1. S. _a._ 2. The BROWN HAIR-STREAK-BUTTERFLY. The _Caterpillar_ of this _Butterfly_ is seldom found: which, I believe, is owing to the oddness of its Shape and Colour, which are exactly represented in the Plate. I took four of them by beating the _Black-Thorn_, and fed them on the same till the Middle of _June_, at which Time they changed into the _Chrysalis_, and the _Fly_ was bred in the Middle of _August_. This _Butterfly_ delights to settle on the _Maple-Tree_, &c. by beating the Branches whereof the _Fly_ will rise, and may be taken in your Net. The Black-Thorn. _Prunus Sylvestris._ Germ. Emac. L. 3. CH. 2. III. CL. 1. S. _a._ 3. The GREEN BUTTERFLY. Mr. _Dandridge_ took the _Caterpillar_ of this _Fly_ at the Beginning of _July_, feeding on the inside of the _Blackberry_ Buds, in which it made a small Hole, whereby it entered, and eating all the inward Part, left the Buds seemingly entire: It fed on them till the Middle of _July_, and then changed to a _Chrysalis_; and in the Middle of _April_, the Year following, the _Fly_ was bred. This _Butterfly_ is most common in and near Woods; it delights to settle on Boughs four or five Feet from the Ground, by moving which the _Fly_ will rise, and if not much frighted will settle on or near the same Place again, by which Means you may take it with your Net. The best Time to catch this _Butterfly_ is from the first to the fifteenth of _May_. The Blackberry, with its Fruit and Blossom. _Rubus, major, fructu nigro._ J. B.
