Description: 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.

Description: Rather odd looking fly. 2 appeared in kitchen last Sunday, today there are five. Body length 6mm, wingspan 9mm. Body hunched down at end and wings held at odd angle. Reluctant to fly and generally sluggish but can walk away quite quickly when a camera is pointed at them. Rather beautiful wings when seen through a camera lens.

Description: Small fly with markings on body and wings.
