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.
