This ' Emerald shiny dung fly' or 'Scathophagidae' apparently hit something... as it looks quite battered.
Seems I have some moire in the eye... any hints on how to prevent it ? Every sharp image I have of it, has this ...

Interesting dent. I don't have an answer for you, but would also be interested in knowing. I have the same issue with a dragonfly I shot a couple days ago. I also should have opened up the aperture and lowered the flash. I think this is the first time I I've had this happen ant it was also on every shot.
The "moire" you are referring to is the many thousand photo receptive units in the compound eye. They are each their own individual eye and make up that pattern. You don't want to prevent it, you want to make it more clear and sharp. Close up for reference:
How strong you see the moirè pattern depends also on the camera. But usually you have some on pictures with regular pattern in it. Especially in architecture photography is it very common. How these patterns build is explaind here very well: https://en.wikipedia.org/wiki/Moiré_pattern
You guessed right, that the tiny facets in the eye, generating the overlapping moiré pattern.
Software like LR, Photoshop Camera Raw, Capture One (many others) have built in functions to reduce the pattern strength.
It would be really funny to hear the story behind the dent. ;)
So, when you come in closer, the pattern should be less because the tiny dots don't overlap anymore ?
the dent, I didn't do it !
;-)
Yes but it's more, they are not that close together anymore. I have no idea, if you can avoid them at all.
"the dent, I didn't do it !"
I would say that too! Just joking! ;)
