No super-Drosophila: Vinegar fly species have a good vision or olfaction, but not both

A team of scientists has systematically studied and compared the eyes and antennae and the associated brain structures of more than 60 species of the genus Drosophila. They found a large variation, but at the same time a close correlation between the two sensory features. The size of the sensory organs is related to the behavior of the mate and host selection.
