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.

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.
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,
