Pointy Nosed, back 6-pack, velcro chested mystery fly

Description:

Does anyone know what this is?It must still be flying around in our house, so I hope that I can have another go at photographing it. It appeared in our kitchen while I was busy and I thought it looked interesting, but disappeared before I had a chance to have a proper try at getting a photo. These are all a bit dark.The "chest" is awesome with those bristly pads of thck hairs. i wonder if it has to grapple something, and needs a strong grip.
