a Sonoran Desert Fly species from the Diptera family. These plugs serve as a means of male-female control during mating interactions.

A peculiar example of mate plugging occurs in Leucauge mariana spiders. Both male and female participation is required to create a mate plug. The male alone cannot create a functional plug. Female participation in creating mating plugs, and her presumed benefit from them, have led to multiple studies of sexual selection on the sexual behavior of L. mariana.
