摘要

Many a scientific study was carried out on the in vivo bioluminescence emission of the firefly. In those studies, the wavelength peaks of different species of firefly were documented at fixed positions—showing no variation. Here we record steady state emission spectra of the Indian species of firefly Asymmetricata circumdata at its normal flashing temperature. An observation of the spectra of different specimens of this summer species recorded over three years reveals that positions of the peaks are not the same; these differ by 9 nm. This non-negligible difference points towards slight changes in the structure of, or in the localised microenvironment around, the enzyme catalyst luciferase in this species itself.
