Ormia lineifrons larva

Ormia ochracea is a small yellow nocturnal fly, a parasitoid of crickets. It is notable because of its exceptionally acute directional hearing. 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 fly is found throughout the southern US and into Mexico, though its exact range is not known.
