The discovery is scientifically significant because the mating behavior exhibited is essentially the same as that of froghoppers today.
Fossils that show behavior of any sort are unusual, and fossils of mating insects even more so….
Only 33 examples of copulating insects are known to exist in the entire fossil record, most of them caught in amber. Until now, the oldest was two tiny flies, what fly fishers call midges, preserved in 135 million-year-old amber from Lebanon. | Source: NYT
