The change is caused by a single gene in the sexual chromosome of males ((RM Tinghitella.

-Flatwing males escape from the parasitoid, but also are not found by females. Instead, they have a 'satellite' sexual behavior -- they attempt to mate females that are attracted by calling males. Currently about 90% of the male crickets in Kauai were of the flatwing morph. This huge proportion of silent satellites +Flatwing males escape from the parasitoid, but also are not found by females.
