Culicoides brevitarsis transmits important ruminant arboviruses, such as Akabane, Aino and bluetongue viruses. The presence of this species has so far been recognized primarily in Okinawa, the southernmost prefecture of Japan. In entomological surveys in 2008 and 2009, C. brevitarsis was collected at 8 sites throughout Nagasaki, Kumamoto and Kagoshima Prefectures. The collection sites are all located near pastures, where the larvae of C. brevitarsis can grow in cattle dung left in the field. C.

Given the risk of arbovirus transmission, the ecology of C. brevitarsis in Japan, such as its distribution range, seasonal abundance and larval breeding sites, should be investigated in more detail.
