Either summer or winter hosts have been known for the Japanese multivoltine gall midges of the genus Asphondylia. We renew the distribution records of these gall midges based on more recent and detailed collecting data that have been accumulated since Yukawa & Masuda (1996). Distributional information of each Asphondylia gall midge is quite important to combine gall midges utilizing summer hosts with those utilizing winter hosts, because host alternation by the gall midges has been suspected. The distributional information indicated two possible combinations between spring-summer and autumn-winter gall midges.
