Fundamental differences in the optical structure of the eyes of nocturnal and diurnal mosquitoes

Land, M F; Gibson, George M; Horvat, J; Zeil, Jochen


We have studied the anatomy and optics of the eyes of a range of mosquito species from the wholly dark-active blood-feeding Anopheles gambiae to the diurnal plant-feeder Toxorhynchites brevipalpis. Consistent with studies by Sato in the 1950s, we find that dark-active and crepuscular species have short fused rhabdoms with a conical construction. This maximises the amount of light the rhabdoms receive from the almost hemispherical wide-aperture lenses. Toxorhynchites, on the other hand, has long...[Show more]
