✦ Synopsis

The electroretinographic visual spectral sensitivity functions in day-active fireflies Lucidota luteicollis and Lucidota atra show a broad green sensitivity and a shoulder in the near-ultraviolet region of the spectrum (Figs. 1, 2) as is commonly found among day-active insects. The nomogram for P530 visual pigment matches the spectral sensitivity curves in the green. The adult L. luteicollis retains its larval bioluminescent light organ which has a peak emission at 562 nm. The 2ma x of the ERG spectral sensitivity does not match the bioluminescent peak (Fig. 1 B) as it does in twilight-and dark-active fireflies. Some relevant behavioural observations with respect to mating are presented.
