Irfanview says subject distance is 384 mm. The same digits are reported by Thumbsplus but with the decimal in a different place.
I think what we need is something that can interpret the EXIF data correctly. I don't have Canon software currently installed, or I'd check with it.
A clue on whether the flash fired might be visible in other foreground. Looking carefully in the vegetation, I don't see clear evidence that the flash was fired. The best place to look is the closest deep shadows.
If the flash didn't fire, I don't think the bug theory has a leg to stand on. I may change my favorite to the hair theory. It could be a hair, as someone said with a follicle and maybe even a flake of dead skin attached.
