Photuris versicolor
''Photuris versicolor'', is a species complex of firefly common throughout the Eastern United States. Fireflies famously use flash-based visual signalling to find mates at a distance and each species of firefly has a unique flash pattern sequence that males and females of the same species use to identify one another. Researchers have documented the ability female ''P. versicolor'' to hunt males of other firefly species by mimicking the flash responses of female fireflies of other species. ''Photuris versicolor'' appear to target males, such as Photinus pyralis, specifically for the lucibufagin steroids that their prey produce.
==Description==
''Photuris versicolor'' are large members of the Lampyridae family, approximately 20–50 mm in length. ''P. versicolor'' are strong fliers with excellent eye sight, which is especially sensitive to light in the near UV (380 nm) and green (550 nm) spectra. Although male and female adults both have luminescence, this species is strongly sexually dimorphic. Females are larger bodied with a larger flash organ than males.
