In spite of the uniform flower feeding habitat of adult hoverflies, their larval feeding ecology is diverse. The genus Chamaesyrphus Mik, 1895, is rare and its larval feeding ecology is entirely unknown. Here we reported larval feeding ecology of Chamaesyrphus japonicus Shiraki, 1956. We found that nine larvae of Cha. japonicus fed on five fruitbodies of ectomycorrhizal hypogeous basidiomycete fungi Rhizopogon roseolus (Corda) Th. Fr., Svensk, 1909, while two larvae of Cha. japonicus fed on two fruitbodies of Rhizopogon luteolus Fr. & Nordholm, 1817. This is the first documentation of the mycophagy in the genus Chamaesyrphus. Gut contents of the dissected larvae contained a lot of undamaged spores, suggesting that Cha. japonicus larvae may be spore transporter of them.

日本松毛虫（Chamaesyrphus japonicus）食用外生菌根真菌Rhozopogon roseolus和R. luteolus（Diptera：Syrphidae）

尽管成年食蚜蝇具有统一的采食栖息地，但其幼虫的采食生态是多种多样的。Chamaesyrphus Mik属（1895年）非常罕见，其幼虫摄食生态学完全未知。在这里，我们报道了Chamaesyrphus japonicus Shiraki，1956年的幼虫摄食生态学。我们发现了9个Cha的幼虫。用五个外生菌根的次生担子菌真菌Rhozopogon roseolus（Corda）Th的五个子实体进食了日本血吸虫。斯文斯克神父（Fr。），1909年，而查（Cha）的两个幼虫。刺参饲喂两种子实体Rhizopogon luteolus大一＆Nordholm，1817年。这是Chamaesyrphus属中的自噬的第一个文献。。解剖后的幼虫的肠内容物含有许多未损坏的孢子，表明是茶。刺参幼虫可能是它们的孢子转运体。
