Photuris versicolor, is a species complex of firefly common throughout the Eastern United States.

Photuris versicolor appear to target males, such as Photinus pyralis, specifically for the lucibufagin steroids that their prey produce.

[3] Photuris versicolor are large members of the Lampyridae family, approximately 20–50 mm in length.

[4] Although male and female adults both have luminescence, this species is strongly sexually dimorphic.

However, sometime after mating, P. versicolor females become unresponsive to conspecific males and begin using flash signalling in hunting.
