It's not easy to get photos of fireflies, but just imagine their flashing from ground level to canopy.

We've been treated to evening displays for days now. Lovely, and unexpected.

Normally, we'd have sucessional waves, from ground to canopy over weeks, not days - so it's a treat to see the night sky full of flashes.

Years ago, in Maryland, we saw similar views in the canopy forest below the house we rented in summer (while during field work). Nice to see that again in our urban ravine forest behind the house.
