July 27, 2006.
This time I examined thick vegetation at the park's border near the Nara river, with a heron circling above me for a while. These flies were quite numerous, especially near water where Phragmites/Typha/Butomus grew. Size 6mm.

Wow, Chloropidae again :)!
Platycephala planifrons ... attacks Phragmites shoots early in the year leading to severe stunting of attacked stems by killing the growing point. Platycephala planifrons was one of the most damaging species found during surveys in Europe. Attack can cause biomass reductions of >50%. Females fly in the summer and are long lived. Eggs are laid in late summer. Larvae hatch in late summer, feed for a limited period, and overwinter.

P.S. I found out Xespok initially took these for Sciomyzidae, too (http://www.dipter...#post_2176).

Identification confirmed! Dmitry, very good short summary of the biology! Addition: Larvae are feeding on bacteria which develop at the growing point of the Phragmites stem/leaves. Compare notes for further pictures of this species. Many publications exist on this species.
