Must be fake (unless you're driving a lens-less camera obscura). There's a region starting from the camera surface until its focal point at which the camera cannot focus objects. This is why macro lenses that have a very small focal length exist. And the insect looks very clear despite being closer than the camera could focus. Also, in a real photo, the mosquito would not look transparent like that. It would look pitch-black like everything else in the photo. The background seems legit to me. It can be produced if you set narrow aperture, short exposure and low light-sensitivity, knowing this was made in a foggy day. But that mosquito is an overlay, IMHO.
