HI I observed a number of these adults in rice fields at Kalimpong(Darjeeling) in INdia. The area is a hilly region at an elevation of 4000 ft. The crop is rainfed upland with no stagnating water. I have not observed this fly in other regions. Can somebody identify the species and give me some indication as to what could be its role in rice fields - pest or saprophagous? chitrashanker attached the following image:  [140.46Kb] Edited by chitrashanker on 28-10-2013 06:01 |

Derbidae (Hemiptera, Auchenorrhyncha)
While others can't climb, using infinite pains, I, gravity turning to jest, Ascend, with all ease, perpendicular planes, Rough or smooth, just as pleases me best. |

In Distant, 1906 it runs to Diostrombus carnosa (Westwood, 1851) (as Drona carnosa, synonymy according to Muir, 1913)

Thank you Dmitry for the ID. Diostrombus carnosa seems to have a blackish abdomen while this is totally orange in colour. At least now I know what keys I have to refer  . Thanks a ton |

At least the type species, Diostrombus politus Uhler, 1896, is recorded on rice (Lee & Kwon, 1977; Rahman et al., 2012)

Yes politus looks very similar (from Rahman et al., 2012); I believe it's not yet recorded from India though.
