Psilota is a genus of hoverflies, belonging to the family Syrphidae, subfamiliy Milesiinae, and tribe Eumerini. These insects are commonly known as flower flies or syrphid flies due to their often flower-visiting behavior and their resemblance to bees or wasps.
Description and Characteristics: Species within the genus Psilota are typically small to medium-sized flies, often characterized by their somewhat flattened bodies and a generally dark, sometimes metallic, coloration. Like other hoverflies, they are distinguished by their unique venation pattern in the wings, particularly the presence of a spurious vein between the third and fourth longitudinal veins. Larvae of Psilota species are saprophagous, meaning they feed on decaying organic matter, often found in tree sap, under bark, or in other decaying plant material. Adult Psilota flies, like many other hoverflies, are important pollinators, feeding on nectar and pollen from various flowers.
Distribution: The genus Psilota has a wide distribution, with species found across various biogeographical regions including the Palearctic, Nearctic, Oriental, and Australasian realms. Specific species have more restricted ranges, but the genus as a whole is quite widespread.
Ecology: Adult Psilota flies are commonly observed in woodlands, forests, and other areas where their larval habitats (e.g., decaying wood or sap runs) are present. Their role as pollinators makes them ecologically significant, contributing to the reproduction of numerous plant species.
