|A Dark Firefly, Lucidota atra|
Lots of folks are noticing the fireflies, or lightning bugs, (actually Lampyridae beetles) out this time of year. Not as many notice the Dark Fireflies that are also out though. These are diurnal, emerging during the day, although usually in dark woods. They use pheromones to attract each other rather than the lights we normally associate with "regular" firefly beetles.
So next time you go seeking fireflies, don't just go looking at night. You can find some Dark Fireflies if you go looking for them in the woods during the day before their light-up cousins are putting on their light at night.
