A recent discovery in the Ecuadorian Amazon has left scientists baffled: a new species of fly that mimics stingless bees. This finding highlights the complexity and richness of the Amazonian ecosystems.
This innovative species, named Ubristes mirabilissimus, belongs to the family Syrphidae, known for its crucial role as pollinators in nature.
With a size ranging from 12 to 14 millimeters, these flies have a dark body and features that evoke bees of the Trigona genus, such as their elongated antennae and robust legs.
Mimicry is their evolutionary strategy to protect themselves from potential predators, deceiving them with their bee-like appearance. This adaptation could be vital for their survival in the competitive jungle environment.
The samples, collected in the Napo province at altitudes between 500 and 590 meters, were studied by Menno Reemer and Ximo Mengual, prominent scientists from the Naturalis Biodiversity Center and the Koenig Museum. According to the National Institute of Biodiversity (Inabio), so far, the species has only been recorded in two locations separated by about 35 kilometers.
The name ‘mirabilissimus’ derives from Latin and translates to “wonderful” or “strange,” reflecting the uniqueness of this species. Experts highlight the rarity of these insects, which often go unnoticed due to their camouflage.
The biological richness of Ecuador, one of the 20 most biodiverse countries in the world, is the result of its strategic location, where the Andes mountain range, the Amazon, and ocean currents converge. This geographical context favors the emergence of unique species like Ubristes mirabilissimus.
Researchers emphasize the importance of continuing the conservation efforts and exploration to discover more about the existing and protected biodiversity in these crucial ecosystems.
