Host was apparently a moth in the Arctiinae subfamily of Erebids.

Spores probably already dispursed and the moth a goner.

The Cordycipitaceae are a family of parasitic fungi in the Ascomycota, class Sordariomycetes. The family was first published in 1969 by mycologist Hanns Kreisel, but the naming was invalid according to the code of International Code of Nomenclature for algae, fungi, and plants. It was validly published in 2007.
