 In 1975, Dr. William H. Cade discovered that the parasitic tachinid fly "Ormia ochracea" is attracted to the song of the cricket, and uses it to locate the male to deposit her larvae on him.It was the first known example of a natural enemy that locates its host or prey using the mating signal.Since then, many species of crickets have been found to be carrying the same parasitic fly, or related species.
