The BLUE ARGUS-BUTTERFLY breeds twice a Year: The first Brood appears in _May_, the second at the End of _July_ and Beginning of _August_. This _Fly_ is very common in most _Hay-Fields_ at those Times, and is easily taken. As for the _Caterpillar_ and _Chrysalis_, I have never yet heard that they have been discovered by any Body. The Green Gage-Plumb. _Prunus fructu rotundo e viridi flavescente, carne dura suavissima._ Miller. L. 3. CH. 3. II. CL. 1. S. _A._ 2. The PURPLE HIGH-FLYER, or EMPEROR OF THE WOODS. Neither the _Caterpillar_ nor _Chrysalis_ of this charming _Fly_ has been yet discovered, although sought after with the utmost Diligence for several Years past. The _Butterfly_ appears at the End of _June_ and Beginning of _July_, and may be taken in _Comb_-Wood in _Surry_, about _Westram_ in _Kent_, and in other Places. It flies like a Hawk, delighting to soar aloft and skim in the Air. When it settles it is usually on some extreme Part of the _Oak_, _Hasle_, or _Ash-Tree_: and what is very singular, I myself have seen twenty of them taken on the same Branch one after another, for although the _Fly_ seems to be extremely wild whilst on the Wing, yet, when settled, you may lay your Net over it with little Trouble.
