The insects got their name because they jump around on plants and shrubs much like little frogs.
"On the mating pair, the male's aedeagus is inserted inside the bursa copulatrix of the female," said the study led by scientists at the Key Laboratory of Insect Evolution and Environmental Changes at Capital Normal University in Beijing.
The rare fossil shows "the earliest record of copulating insects hitherto," and "sheds light on the evolution of mating behavior in this group of insects," it added.
Namely, it shows that the creatures' genitalia and mating position have stayed the same for more than 165 million years, the authors said.
