Thanks tristram!

So this should mean that the fly is either extremely fresh (to me at least, it doesn't look like that, since the wings are already damaged a bit), or much more likely, that the ptilinum failed to collapse after use, right?

Are there any known pathologic reasons for that, or does it sometimes simply happen accidentally.
