Is this
the bioluminescent one we saw "winking" at us when we turned off Margarethe's blacklights?

 
Probably,
...but there are two species, in two different genera that have these bioluminescent spots, and apparently only looking at the genitalia will distinguish them conclusively. I also saw one high in the tree that I hung my sheet from at Pena Blanca when I was taking everything down. It was moving around in the branches - looked like two bright little eyes!
