No, should be a tachinid.

Interesting to see some HK flies, thanks!  Unusual bend in M vein, I think. |

Looks like one of the Dexiini, let us here also the more experienced people. Attract them by renaming your title to Tachinidae.

Thx all!! how can we identify Tachinid spp. easily ? any obvious outlook feature? it that unusual M vein? i just know that its post-scutellum is prominently convexly developed and can only be examined under microscope!! any suggestion? Xespok, any more information to show that it looks like Dexiini? hope to know more about that!! thx!! |

Tachinids are calyptrate flies with a bend in vein m (but not always) and with large, strong abdomenal bristles (but not always) and with a subscutellum (99%) which can't usually be seen in photos.  The dexiines tend to be longer-legged than other subfamilies but again this isn't a rule - just a rule of thumb.  Often tachinids lay eggs that immediately hatch - the emerged larvae then go looking for a host or lay on the food waiting for a host to come by. I'm not sure about the oriental region but tachinids are often hard to identify outside Europe  Theo will know more. |

IN Europe, this would be Dexia vacua. There are many Oriental species of Dexia. SO I guess it's one of those. Theo |
