Two species of flies, Drosophila melanogaster and Drosophila simulans, can mate. They usually do not mate, however, even if they are kept together in a laboratory. Males court the females of both species, but the females prefer to mate with males of their own species. Which isolating mechanism does this describe?

Behavioral isolation. This is when animals that can otherwise mate do not mate because of differences in courtship behavior. These animals choose to mate with animals of their own species.
