I made a really puzzling observation today. I found a very small flying insect (~1mm) at a friends house. I could not identify if it was a really small fly, wasp or something else. Intrigued; I ended up putting it inside a foldscope.

As luck would have it; I squashed the big and a whole lot of hemolymph came swarming out. Now, I squash many bugs under a foldscope – nothing unusual – usually I see lots of lipid (fat droplets). But this time; something was special. All the droplets were glowing – yes, you read it right. Glowing. I was so thrilled – I almost forgot to take any pictures. I only took these three images.

I have imaged so many insects, never seen hemolymph like this. I will try to sample the same insect again; but would love to hear thoughts others might have.

@Laks: in the past we discussed bilirubin before. Any connections to the same.

Cheers
