Looks more like the family Phoridae than a midge, in which case refer the specimens (not the photographs) to Dr Henry Disney at Cambridge University, England. Small flies such as these will need to be mounted on microscope slide and possibly dissected for a generic or species identification.
Above person are right, this may be phoridae. But need to identify then mount it in a glass slide and then send picture one by one..means wing, legs, antennae, genitalia.
It is imposibe identify with these images, wing venation or other characteristics not appreciated. But in fact appears to be a Ceratopogonidae (not Phoridae).
It is impossible to determine this fly without seeing wing venation. As you can see preparation of small insects is very important for the precise determination of insects.
Phoridae or Ceratopogonidae but other flies could also be.
The images are still of poor quality to identify the specimen. However, in picture 6 & 7 you can see the venation (rotated the image for better seen). Undoubtedly belongs to Ceratopogonidae. You can find more information in http://campus.belmont.edu/cienews/cie.html
Hello. It is from the Ceratopogonidae Family. See this paper for more information: Clave gráfica de adultos del generos hematofagos de Ceratopogonidae... Ronderos et al. 2004.
