An investigation of the opsin gene complex in scorpionflies (Mecoptera: Panorpidae)

Panorpids have the greatest visual acuity of all Mecoptera. However, we know very little about the opsin gene complex and the evolution of color vision within this family. Most insects have at least three opsin copies, but duplications of these copies are present in other insect groups. We present data on opsin genes within the major species groups of panorpids, and look for correlations between the presence of opsins and the wing banding patterns within the species groups. This research will provide the foundational data for understanding the evolution of color vision in a charismatic group of insects.
