Moths attacked by Fungus

Hi Kevin,
It is difficult to ascertain if these insects are actually Moths, but that is a likely place to start.  They are not, however, undergoing metamorphosis.  They have been attacked by entomopathogenic fungi, and you may see numerous additional examples of this phenomenon on BugGuide.  Flies and spiders seem to be especially prone to fungus attack, but other insects and arthropods may also be afflicted.

Moth attacked by fungus in cave

Thank you.  There are over a dozen other moths in the mine shaft in various stages of attack.  There are some that have died and fallen to the ground as well as a couple in what must be an early stage.  Anyway, I appreciate your solving our little mystery.
