Hornet Mimic Hover Fly - Volucella zonaria



To identify flies to family level use a simple wing venation key such as A Key to the Families of British Diptera, an AIDGAP by D. Unwin, published by the FSC and available as a free download (scroll down to the titles list) or a more detailed key which includes many physical characters such as The European Families of the Diptera by P. Oosterbroek. The expert dipterists on the DipteraInfo forum are also very happy to identify, often to species level, from good photographs.

Scientific Name: Volucella zonaria (Syrphidae Volucellini).


English Name: Hornet Mimic Hover Fly (Hover Fly family, Tribe Volucellini).


French Name:

5 Key Characters:
  • one of the largest hover flies.

  • wings are orangey-yellow at the base and have a dark patch near the tip.
  • comes indoors quite frequently.

Lookalikes: Volucella inanis, which is smaller, does not have chestnut colouring and is yellow underneath, on sternite 2 (V. zonaria is black).

Status: Fairly common.

Close up detail to show wing venation. The pattern of veins on fly wings is key to identifying them to family level. Each family has a different pattern of veins. All hover flies have wing venation similar (but not identical) to that shown above.

  1. I noticed this beautiful hoverfly yesterday afternoon in my garden on my giant daisies. Haven't seen it before here in Attika, Greece.

    1. They thrive in gardens. I used to get them even in London!
