Found this
Platycheirus manicatus in the garden today...any idea what would cause the swelling/blister on its eye?
That's got to be sore...do flies feel pain?

A drop of something. Perhaps honeydew?

Poor photo, but from the front it looks like a blister or something..

Never seen anything like this - it looks like there is some of the eye missing. It's possibly a developmental problem, but perhaps an accident with some caustic liquid?
I should think it's aware that there's a problem, but generally I don't credit flies with enough brain capacity to register pain as such. Otherwise I'd have to stop collecting them ... :|

So let's presume flies don't feel pain, so we can keep pinning them.
Did anyone ever register the amount of stress-hormones in a fly, while being killed in a bottle? :|

Something hypertonous enough might be able to extract the liquid contents from the head causing the eye to collaps?
