Females Sport Penises in Genital-Swapped Insects

 Science, April 2014

Ecologists spelunking in a Brazilian cave have found a new variety of insect with an unusual sex life. Females of the newly discovered genus Neotrogla, 3-mm-long flylike insects, boast large, penislike structures called gynosomes. Although other animals such as seahorses take on reversed gender roles, species in the new genus are the first to be found with swapped genital structures.
