The egg-batches of Chrysops vanderwulpi kitaensis Hayakawa, 1982,and C. nigripes Zetterstedt, 1840 were collected from marsh plants in Hokkaido in the late July of 1982. Thirty-three egg-batches of C. vanderwulpi kitaensis were found on almost erected leaves or stems of 5 species of plants, mostly of Phragmites communis Trinius, which grew in water off-shore. On the other hand, two egg-batches were found on the underside of horizontal leaves of Sium suave Walker. The average height of oviposition sites was 14.1cm and 22.5cm above the water surface in C. vanderwulpi kitaensis and C. nigripes, respectively. The egg-batches of both species were quite similar each other; dark brown to black in color, and flat and very elongated in shape with monolayer of eggs. Average number of eggs per batch was 85.5 and 99.0 in C. vanderwulpi kitaensis and C. nigripes, respectively. Eggs of both species were parasitized by wasps.
