What are Hoverflies?

About Hoverflies:

• Hoverflies, sometimes called 'flower flies' or 'syrphid flies', are any member of a family that contains about 6,000 species of insects in the fly order, Diptera.
• Their various common names refer to the behaviour of hovering around flowers.
• They are found worldwide, from temperate regions to tropical environments.
• Hoverflies, with their yellow markings, resemble wasps or bees but do not bite or sting.
  • They can be readily distinguished from wasps and bees by their single pair of wings.
• They are distinguished from other flies by a false (spurious) vein that closely parallels the fourth longitudinal wing vein.
• The species vary from small, elongated, and slender to large, hairy, and yellow and black.
• They also have a typical fly head with short antennae and bulbous eyes.
• Beneficial Insect:
  • Adults feed on nectar and pollen, making them important pollinators in a variety of habitats. 
  • The larvae of many species feed on aphids (soft-bodied insects that use their piercing sucking mouthparts to feed on plant sap), mites and small insects helping to control populations of these pests.
  • Others are efficient nutrient recyclers.
