The Syrphus opinator has no specific common name of its own, like many, many other insects. It is a Hoverfly, so called because it can be seen hovering or nectaring at flowers. Some people called these insects Flower Flies or Syrphid Flies as they belong to a family of insects called Syrphidae. Although they look like a bee or wasp, that is only to ward off predators. They are totally harmless to humans. |
