Fossil records of mating insects are fairly sparse, and therefore our current knowledge of mating position and genitalia orientation in the early stages of evolution is rather limited.

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. Ren adds, "We 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."
