I have many pictures of two specimen (presumably a male and female)

The one with bent wing has this appendix which I think uses to penetrate my luffa fruit skin and lay its eggs or maybe that's the male's organ

I think the little vestigial wings mean it's a fly, right? Wasps should have another functional pair of wings instead. Sometimes it's hard to tell but I only see 2 here.

    Yes, they are called halteres, just learned this today. Closest I could find was Dacus longicornis
