Common Drone Fly Eristalis tenax

This is the ultimate world traveler of hover flies—the most widely distributed syrphid species in the world, found on every continent except Antarctica. It has conquered the globe like few other insects, with established populations everywhere from Europe and North America to Australia. What makes it even more remarkable is that it's highly migratory, with individual flies undertaking vast intercontinental journeys. You might spot one pollinating flowers in a European garden one season, then find its cousins working the same flowers in an Australian meadow or high in the Himalayas. Its cosmopolitan range is a testament to its adaptability and resilience.
