firefly

LITThe common eastern firefly Photinus pyralis flashes with a peak near 560 nm. Field measurements average 562.8 nm, ranging 558.4–568.1 nm (PMC5014620). Lall et al. (1980) found most dark-active species glow green (<559 nm) and most dusk-active ones yellow (>560 nm). In the test tube, luciferase light shifts toward red as pH drops: a pH-sensitive component near 560 nm and others near 620 and 670 nm.

MODELEmission is a Gaussian at the slider's peak, mixed with a red component as pH drops; colours come through CIE. The fireflies sync loosely (a Kuramoto toy). Nesting: an orange low-pH flash core, a purple dusk, a green meadow, the yellow flashes, black night.
