Spotted more than one of this kind of fly in a ground floor house since a week ago, it has a black and white mark on his back, pointed wings, and some kind of stinger. In the few minutes I was photographing the specimen, it seems that the stinger had been detached. Very small between a 0.2 and 0.3 inches long.

The "sting"

I think the "sting" is perhaps a distal segment of the abdomen extended for egglaying - it may have been retracted in the later photos.

yes most likely it's a female and these are the apical segments of the abdomen containing the ovipositor
