Flash signaling characteristics include differences in duration, timing, color, number and rate of repetitions, height of flight, and direction of flight (e.g. He said that natural selection would not favor mimicry for any intrinsic value, but that it would favor behavior that led to more food, in this case, capturing males.

While all known fireflies glow as larvae, only some species produce light in their adult stage, and the location of the light organ varies among species and between sexes of the same species. The enzyme luciferase acts on the luciferin in the presence of magnesium ions, a chemical called adenosine triphosphate (ATP) and oxygen to produce light. When Photuris fireflies have eaten Photinus fireflies and produce lucibufagins , hungry spiders reject them.

Nonetheless, their mating habits follow the firefly pattern, with males on the wing searching for females hidden in the dark. Firefly populations are shrinking, and the search for luciferase is just one of the reasons. By mimicking the flash patterns of other firefly species, the female lures unsuspecting males in closer. They watch for females to respond to their pattern with single flashes.".
