Just photographed this fly inside my house, and looked up on the internet to find what it was. Will go and liberate it now that I know it is a “good” insect. Thought that you might like to see the photos.

Dear Heuchan,
Thank you ever so much for sending your excellent images of a Threelined Hover Fly,
Helophilus seelandicus, to our site, especially since you did not require an identification.  We have but a single image of a Threelined Hover Fly in our archives, and it is a ventral view, which is not ideal for identification purposes.  Your dorsal views are marvelous.  According to Landcare Research:  “Attracts attention because of its noisy flight  Important pollinator of flowers  Larvae are rat tailed maggots which live in liquid containing rotting plants or animals.”  According to iNaturalist, it “is a native hoverfly of New Zealand. The name corresponds to the three black lines behind the insect’s head.”  We are tagging this posting with the Bug Humanitarian Award since you captured and released.

Hi Daniel,
Thank you for your reply to my email re the Threelined Hover Fly.
I give you permission to use my photos, if you wish in your “What’s that bug” archives.
I have also included two extra images taken after I liberated the fly onto some retaining wall timber. I don’t know how long the fly stayed there, it was gone about 30 minutes after liberation. Didn’t stay “on watch”, was getting cold, late afternoon time.
Thanks again for your informative email,

  1. Hi Daniel
    I live in Katikati in the north of the North Island of New Zealand. I just found a hover fly on the inside of my window. I have never seen one here before so was worried one of our B & B guests had bought it from overseas in their luggage. I am so pleased to read on your website that it is a local and your picture is very clear for identification purposes. Thanks for the information.

    Just caught and released a large hover fly in Piha. Orange legs and bright yellow stripes.

    Thanks for allaying my fears too, pretty sure that’s what I just caught and released. Waiheke Island.

    Lovely Photos – Just found one near Ngaruawahia, and we live organically on a lifestyle block plant a lot of trees etc so insect thrive here.
