It has been named Buccinatormyia gangnami, in honor of the most famous song by the South Korean singer PSY, the new fly identified based on the analysis of six fossil footprints found near Jinju, South Korea. According to the researchers, it was a fly that lived during the lower Cretaceous period (between 145 and 100 million years ago), similar to the common house fly, which had a 5 mm trunk.
The insect boasted a dark abdomen characterized by the unusual presence of four lighter points on each side, an anatomical characterization that probably served this fly to imitate wasps or animals similar to the latter considering that wasps, in the early Cretaceous, were quite rare. The Buccinatormyia gangnami belonged to the family of the Zhangsolvidae, of which it is now the third known species, a family of dipterans which seems to have prospered during the first Cretaceous and whose components then became extinct for unknown causes.
Some flies with long proboscis have managed to survive to the present day but most of these flies and flying insects have most likely become extinct because they were unable to adapt to a world dominated by angiosperms as, at least initially, they were all associated with gymnosperms for food.
The research was carried out by Alexander Khramov, of the Paleontological Institute of Borissiak (Moscow).
