Photinus pyralis fireflies signal to each other at dusk in early summer. Males of this species draw J-shaped swoops while females signal their interest from the grass. The common name "big dipper firefly" stems from this species' distinctive flight pattern. This photograph is a composite of long exposures taken over a 10-minute interval.
