Will need to look this one up -- I can't remember the differences among the Texas fireflies. :)
Hard to see the marking on the pronotum in this shot, but it runs down the center of the pronotum from the head to the elytra
Big Dipper Firefly
I see one of these every year I visit...I can't figure it out. It's driving me crazy. I need to just collect one.
