Nail flies standing on a dead boar on the snow were observed by a guard from the Pyrenees National Park, in France, during health surveillance in the Ossau Valley in February of this year. But it’s not just any fly!, says the park.
It is a Thyreophora cynophilaalso known as “bearded vulture” flies and their most common characteristic is having a bright orange head.
Considered extinct since 1836 and included in the list of extinct species of the International Union for Conservation of Nature (IUCN), this fly is considered a ‘scavenger’.
Since 2018 the entomologist Laurent Pelozuelo, (Paul Sabatier University of Toulouse) mobilizes actors to investigate the species on the French side of the Pyrenees.
“The bearded vulture fly is especially active in winter, the cold does not seem to bother its larvae that feed on decomposing carcasses in the snow. The putrid remains of large mammals, wild or domestic”.
The European park detailed that the observations thrown are “extremely rare” and important for the knowledge of the species; and finally exhorts:
“Do you see this fly recognizable by its orange head? Remember: photograph it, locate it (date the observation), and send this information Mr. Laurent Pelozuelo via [email protected] “.
