A new species of flower fly, named Ubristes mirabilissimus, has been discovered in the Napo province of the Ecuadorian Amazon by researchers from the Naturalis Biodiversity Center, including Menno Reemer and Ximo Mengual, alongside scientists from the National Institute of Biodiversity (Inabio) and the Museum Koenig Bonn. This species, part of the Syrphidae family, is known for its important ecological roles, particularly as pollinators. The discovery highlights the rich biodiversity of the Amazon and the ongoing efforts to catalog and understand these ecosystems.

Ubristes mirabilissimus is particularly notable for its mimicry of stingless bees, which may aid in its survival by deterring predators. Measuring between 12 and 14 millimeters, this flower fly exhibits a dark body with morphological features that closely resemble those of neotropical bees from the genus Trigona. The study of such mimetic species can provide insights into evolutionary adaptations and ecological interactions within their environments.

This discovery not only emphasizes the ecological significance of flower flies in pollination but also the critical need for biodiversity conservation in the Amazon region, which faces threats from deforestation and climate change. Researchers hope that understanding the role of species like Ubristes mirabilissimus will contribute to broader conservation efforts and the preservation of ecological balance in these vital ecosystems.
