    “…The in vivo peak emission wavelengths of bioluminescence are reported for 15 species of American fireflies. A spectrophotometric study of the dorsal light organs of 155 specimens of the Jamaican firefly Pyrophorus plagiophthalamus showed three distinct color distributions with peak emission wavelengths at 550.1 ± 1.5 mµ, 556.8 ± 1.4 mµ, and 562.4 ± 1.0 mµ. …”

    “…Here, we report evidence for the occurrence of chimeras in a celebrated realization of natural synchrony: fireflies. In video recordings of Photuris frontalis fireflies, we observe, within a single swarm, the spontaneous emergence of different groups flashing with the same periodicity but with a constant delay between them. …”

    “…[Image: see text] The luciferase isolated from the firefly Photinus pyralis (Ppy) catalyzes a two-step reaction that results in the oxidation of d-luciferin accompanied by emission of yellow–green light with a peak at 560 nm. …”

    “…We examined the phenological patterns of a highly seasonal group of fireflies (Photinus spp., predominantly P. pyralis) over a 12-year period (2004–2015) across 10 plant communities to determine whether interacting drivers could explain the variability observed in the adult flight activity density (i.e. mating season) of this species. …”
