Hi there. This photo was taken in the autumn here, late in the day. The fly is on a Juncus rush, near a wetland area, with lots of native vegetation dominated by manuka. Hope the photo is clear enough.

Dear Gay,
We believe this is a Tachinid Fly in the family Tachinidae.  See BugGuide for additional information.  The larvae of Tachinid Flies are internal parasites that kill their insect and arachnid hosts.  Generally each species of Tachinid Fly is very host specific, so they are important biological control agents.

Hi Danial.
Thanks very much for that information. Confirms what our local bugman suggested, but interesting to hear that these flies are host specific and potentially a part of controlling pest species. Your time on this one is much appreciated. That’s an excellent website and resource you have there.
Cheers, Gay
