Female "femme fatale" Photuris fireflies mimic the photic signaling patterns of the smaller Photinus, attracting males to what appears to be a suitable mate, then eating them. [14] This provides the females with a supply of the toxic defensive lucibufagin chemicals. [28] Many fireflies do not produce light.
Photuris is a genus of fireflies (beetles of the family Lampyridae). These are the femme fatale lightning bugs of North America.This common name refers to a behavior of the adult females of these predatory beetles; they engage in aggressive mimicry, imitating the light signals of other firefly species' females to attract mates – but Photuris use it to attract, kill and eat the unsuspecting ...
During the adult stage of their lives, most Photinus fireflies do not eat, so all activity is fueled by energy that is consumed and subsequently stored during the larval stage; this becomes especially important regarding reproductive activity. Consequently, these nuptial gifts are a big factor in determining which male fireflies females choose ...
Fu also noticed some of those male fireflies were making female flashing signals at that time. Li, Fu and their colleagues decided to investigate further by conducting experiments involving 161 webs.
The firefly is probably the Earth's most famous bioluminescent species, with over 2,000 individual species. Here's how they make their light.
Female fireflies of the genus Photuris emit the same light signals that females of the genus Photinus use as a mating signal. [32] Male fireflies from several different genera are attracted to these mimics, and are subsequently captured and eaten. Female signals are based on that received from the male, each female having a repertoire of ...

When males of P. carolinus detect a female response, a cluster of males forms around the female. When she lands, the males land nearby but not directly on top of her. As many as 20 males may energetically walk, flash, and attempt to mount the female or nearby males. The female does not necessarily mate with the first male to reach her, but may ...
