Last night was warm and balmy, the air filled with fireflies.  These winged beetles emit a yellow light by the process of  bioluminescence. This chemical process produces cold light, with nearly 90% of energy going directly into light production.

To me they are quite simply marvels, a natural light show and impossible to photograph
