just saw very similar ones on a stink bug from Madagascar.

but this is not a characteristic exclusive to Akanthomyces. Paecilomyces/Isaria exhibits similar micromorphology, which seems a more likely fit given the lack of the long, wiry synnemata which should accompany Akanthomyces-style anamorphs.

I’ll admit, I’m not the best person to be judging this. Jonathan should have a look.

I’m doubting Akanthomyces for a few reasons, namely the lack of a sure host ID, absence of synemmata, and what appears to be more spotty, superficial growth, as opposed to structures arising from a host totally enveloped in fungal tissue. The tubular things attached to the right side don’t look particularly bug-ish either…

I’d bet it’s conidial, but more than that, I don’t know.

I’m pretty sure it’s a moth of some sort…

What is this on?
