Iolaus silas (II)

We came across this Southern Sapphire warming itself up in the early morning at Cumberland. It was a very fresh looking specimen, with a lovely pleated texture. I suspect it was recently emerged. Having warmed itself up it disappeared in a flurry of white and iridescent blue.
I had done a previous post on the Southern Sapphire, where the food plants are mentioned, but to add a few historical deatails: the sp. was first described by Westwood in 1851 as Anops silas then reassigned to the genus Iolaus Hubner (1819).
Incidentally, Iolaus was the nephew and general helper hand of Heracles. Perhaps Westwood invoked Silas, a name which derives from the forests or woods.
