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 ...
Certain species of firefly that do not themselves produce lucibufagins have been observed to eat other species of firefly that do produce the steroid to gain the defensive properties for themselves. [2] The lucibufagins are a set of three related compounds (lucibufagin A, B, and C), and are in the same structural class as the bufadienolides. [3]
Most fireflies hibernate as larvae. Some do this by burrowing underground, while others find places on or under the bark of trees. They emerge in the spring. At least one species, Ellychnia corrusca, overwinters as an adult. [9] The larvae of most species are specialized predators and feed on other larvae, terrestrial snails, and slugs.

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 ...

The genus Photuris is often called "femme fatale fireflies", due to the females' habit of imitating other "lightning bugs'" flashes, to attract, kill, and eat them. Their prey includes such unrelated Lampyrinae like rover fireflies ( Photinus ) or Pyractomena .
