Description:  Sepsids are small, glossy black flies that are usually associated with dung or decaying plant or animal material.   In most species, the front of the abdomen is narrow giving them the appearance of small ants.   They also can be reconized by the absence of maxillary palps and the presence of a single dark spot on the costal margin of each wing near the tip.
