When looking up, don't forget to look down

A keen-eyed observer at the May 31 Explore the Stars noticed a glow on the sidewalk that turned out to be a caterpillar with a bio-luminescent belly. I tried to take photos, but getting a good focus in the dark was difficult. Still, I got close.

This close up captures the color of it's glow. I think this was a 5-10 second exposure.

Curious observers soon arrived and examined the sight with their red flashlights, which lit up the scene. 

I quickly realized that some context was essential to the photograph. The shadow of my tripod can be seen next to the glow.

A friend tells me that most likely it's parasites in the caterpillar that are creating the glow -- another subject to look up sometime.
