在辽宁省蚕科所栗蚕保存育种过程中,发现栗蚕蛹体内有寄蝇幼虫,7月吐蛆后人工埋入或自然钻入土中化蛹,并罩笼;翌年6月初羽化;采集成虫,形态分类鉴定为分布日本的白毛蚕寄蝇Sericozenillia albipila,为中国新分布纪录属和种;首次记述该种雄性成虫外形特征,并给出雌性成虫主要特征;栗蚕是其新寄主。研究材料保存在沈阳师范大学昆虫标本室。

The tachinid larvae （Diptera, Tachinidae） were found in the pupae of Dictyoploca japonica Morre, which is a new host from Sitaizi, Fengcheng, Liaoning, China, and emerged out of the pupae in July, then got into or were buried in the soil depending on whether the condition is natural or artificial for pupation through the winter. And in the next early June, the adults emerged from the soil. The tachinid specimens were collected and recognized as Sericozenillia albipila （Mesnil, 1957）, a newly recorded genus and species in China. The male is described for the first time here, and remarkably distinguished from the female with the following morphological features： prosternum and katepimeron hairy; anepisternum, katepisternum and sternite 1 with black hairs; synternite 1＋2 and tergite 3 without median marginal setae. The specimens examined are preserved in the Insect Collection of Shenyang Normal University （SYNU）.
