[13][19] Adult lampyrids have a variety of ways to communicate with mates in courtships: steady glows, flashing, and the use of chemical signals unrelated to photic systems. Future US, Inc.

In one species, for example, the male's signal is two brief flashes two seconds apart, and the female's response is a single brief flash one second after completion of the male's signal. In a further development, female fireflies of the genus Photuris mimic the flash pattern of Photinus species to trap their males as prey. The females of one group of North American fireflies, called Photuris, are known as femme fatales because they lure unsuspecting males to their deaths. The male Big Dipper hopes this bit of skywriting will get him noticed by females hiding in the grass. Photuris females enjoy munching on males of other genera. When fruit flies were treated in the laboratory with lucibufagin, spiders either left the fruit flies alone or only tasted them.

[12] All fireflies glow as larvae, where bioluminescence is an honest aposematic warning signal to predators. [22][15] When flash signals are not sufficiently distinguished between species in a population, sexual selection encourages divergence of signaling patterns.
