Fig. 1 in Review of the firefly visual system (Coleoptera: Lampyridae) and evolution of the opsin genes underlying color vision

Fig. 1 Top: Summary of known sensitivities for UVS and LWS opsins (from the ERG data) and luciferase color emissions (only fireflies with available ERG and emission data are included). Bottom: Visual spectrum (in nm). White bars indicate UV and LW sensitivities based on available ERG data for fireflies in top; black bar indicates luciferase emission spectrum from top
