This is Riverbend Ponds! You’ll only be able to see them between mid-June and mid-July, the eclosion is brief but magnificent

This population exhibits several cohabitating behaviors over the course of a single evening: long, streaky flashes coincide with stationary glows and marauding doublets

With these stacks and 3D reconstructions of the flash trajectories (from the 360deg. GoPros seen in the center of this image) we can compose quantitative descriptions of flash pattern characteristics and describe a population

Here we’re looking at 45 30-second exposures stacked upon each other from the same perspective

On some evenings they ripple and radiate across the whole wetland

This has to be one of the densest firefly populations in Colorado
