The female is attracted by the song of the male cricket and deposits larvae on or around him, as was discovered in 1975 by the zoologist William H. Cade.
The tiny parasitic fly Ormia ochracea has become a model organism in sound localization experiments because of its unique ear.
On the island of Kauai, females of a species of parasitoid fly, Ormia ochracea, respond to the stridulation mating calls of male field crickets (Teleogryllus oceanicus) by locating the crickets and then laying their lethal larvae on them.
