Just surfing around picking up a few more questions for the trivia contest later tonight in the "Firefly Dinner". We have rain, so who knows what we'll see...but we're an adaptable bunch.
Did you know that the female firefly sits in the grass, and the male is the one flying around? The male has a different signal than the female firefly (that sounds familiar). There is an Asian firefly that beats in sync with other fireflies in the area. Links from here.
Also, did you know that Britney Spears' mom is Lynne and Christina Aguilera's is Shelly? Me neither. We have to find trivia questions that will appeal to all ages *grin*.
The lighting agent in fireflies, luciferin, can be used to detect bacteria. It is used in medical work, and NASA is even considering using it to detect for life on other planets.
