Insects engaged in missionary sex positions over 165 m years ago

Washington, Nov. 7 : Scientists have discovered the oldest fossil depicting copulating insects and found that they engaged in sex in missionary position in early stages of evolution.


In this study, the authors present a fossil of a pair of copulating froghoppers, a type of small insect that hops from plant to plant much like tiny frogs.

The well-preserved fossil of these two froghoppers showed belly-to-belly mating position and depicts the male reproductive organ inserting into the female copulatory structure.

This is the earliest record of copulating insects to date, and suggests that froghoppers' genital symmetry and mating position have remained static for over 165 million years.

Dong Ren from Capital Normal University in China said that they found these two very rare copulating froghoppers which provide a glimpse of interesting insect behavior and important data to understand their mating position and genitalia orientation during the Middle Jurassic.
