“…Lately, BL emission spectra were recorded from Indian species of firefly Asymmetricata circumdata showing a narrow yellow peak at 579 nm (Goswami et al, 2015). They also show a diffraction pattern of the emission with a central principal maximum as predominantly yellow.…”

Bioluminescence in fireflies is essential for sexual communication, and each species has evolved a specific bioluminescence emission capable of being detected by its visual system. This spectral "tuning" between visual sensitivity and bioluminescent emission has been established in 14 species of North American fireflies inhabiting diverse photoecological niches. Here we extend that research to three Brazilian species. Macrolampis omissa inhabits the Cerrado (savannas), while Photinus sp1 and Pyrogaster moestus are often sympatric species inhabiting borders of mesophyll rain forests and secondary growth. P. moestus particularly favors humid areas of the forest. M. omissa and Photinus sp1 are twilight-active fireflies emitting yellow bioluminescence. P. moestus is a "twi-night" species emitting green bioluminescence.It initiates flashing at the end of twilight and continues activity into the night. The visual spectral sensitivity of dark-adapted compound eyes in these three species is similar, showing a maximum in the yellow-green wavelengths and a secondary peak in the near-UV, suggesting the presence of two receptors. The bioluminescence emission spectrum in each species is tuned to its yellow-green visual sensitivity peak.Green chromatic adaptation experiments on Photinus sp1 and P. moestus suggest the presence of a blue receptor. The presence of near-UV, blue, and long-wavelength receptors in the compound eyes would enable a trichromatic color vision in Brazilian firefly species active in dim illumination.

“…A striking finding in recent times has been the appearance of a narrow strong line at 591 nm in the emission spectrum of this species; it has been hypothesized that the emission of this line is akin to that of a random laser 6 . Very recently, the steady-state spectrum recorded for another Indian species, Asymmetricata circumdata in a high-resolution spectrometer has shown the peak wavelength at 570 nm, while the same on a colour film in a glass spectrograph revealed the peak at 579 nm between green and red bands, prompting speculation that a sharp line might exist in the emission spectrum of this species just as in the case of L. praeusta 7 .…”

Coherence of the Light of Firefly<i> Luciola praeusta</i>

Firefly bioluminescence has given rise to several curiosity-driven as well as application-oriented studies. The emission spectrum of the Indian species of firefly Luciola praeusta Kiesenwetter 1874 (Coleoptera : Lampyridae : Luciolinae) has been shown to consist of two broad green-and red-coloured sectors, with a narrow yellow one in between. Here we present interference patterns of light of this firefly species using a Michelson interferometer for different positions of the two reflecting mirrors, up to a path difference of 11.5 cm. Next we employ Young's double-slit method with the lantern of the firefly as the source at pinhole separations of 160, 170 and 180 m. From the fringes obtained in these two sets of experiments, we conclude that the light of the firefly exhibits excellent temporal as well as good spatial coherence properties.
