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 ...
In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus Vibrio; [2] in others, it is autogenic, produced by the animals themselves. In most cases, the principal chemical reaction in bioluminescence involves the reaction of a substrate called luciferin and an enzyme , called luciferase .

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 ...
What do you call them: firefly or lightning bugs? It turns out they are the same insect! We explain the regional difference in how they are named in America.
The unique luciferin used by glowworms is synthesised from xanthurenic acid and the amino acid ‘tyrosine’, setting it apart from other known bioluminescent systems, including those of fireflies, which typically utilise D-luciferin. [17] The bioluminescent systems of glowworms and fireflies have distinct evolutionary origins.
