I was called upon by my daughter to remove a large-ish moth from her bedroom this evening, which I did, using the glass-and-card method (primarily to avoid injuring the insect during capture and relocation).
As I turned to leave the room with the captive moth, I noticed two tiny, glittering brilliant pink jewels on its head - after a little bit of moving around and changing angles, it became apparent that these were cats-eye type reflections from the eyes (from those compound elements pointing in my general direction, appearing when the light source was more or less behind my head.
So I took a flash photo of the bug in the glass - and here it is - when insects get their photos taken with a flash, they suffer from red-eye, just like everyone else.
