Litet upphetsad först pga de centrala svarta strecken/punkterna mitt i varje facett i det ljusa området mitt i bilden. Är det en titt ner i facetternas bottnar? Nu luttrad, samma svarta streck/punkter finns ju också i kitinskalets gropar/upphöjningar, så det bör väl vara en artefakt av blixten. Eller, vad tror du?

100% crop of the compound eye of the flower beetle in the previous picture, however not the same picture.
At first I was a bit excited due to the black lines/dots in the centre of every facet in the middle of the light area. Was it a look to the bottom of the individual facets? Now calmer as I discovered the same lines/dots in the small holes/heights of the chitin skeleton. It must be an artefact from the flash. Or, what do you think?

Lennart Fahlén, in his comment, writes that he believes that the artefacts are reflections of the camera. It is possible that he is right. The flash could turn the surfaces into small mirrors??
