unknown black and white fly

[I Gary I]

Hi folks,I registered here as the identity of this fly has been really bugging me,I've tried searching but have drawn a blank.It has a sort of trumpet like snout which you can't see in the pictures,I thought it was a little unusual although it could be common enough and I just have not encountered one before,hope you guys can help.
Cheers
Gary

Will be hard to tell what species it is from your photo's sorry, but what i can tell you is its heavily infected with Entomophthora muscae . Which is a fungal disease that affects several species of fly including the common house fly. the white on the abdomen are its spores. The latin translation turns out at Entomo- which means insect, -phthora which means destroyer, so this is the "insect destroyer." Muscae means "of the fly."

The snout sounds like the hoverfly Rhingia... as Dogghound says, it's really fungified, so without being able to see the abdomen it may not be possible to be sure.

Thanks guys I knew it looked a little odd,does this mean that the black colouration is natural and the white is fungal or is the the black also a factor of the disease?The head,thorax,legs and wings were black and only the abdomen looked to be affected by infection.

The white part around the abdomen are the spores. The darker colour is its more natural colouration. Although the snout (Proboscis) is likely to be held in a more erect position due to the infection.
