I think that this is a typical arbustorum male. |

I too would have said probable arbustorum, just from the general look of this the fly. But would have needed to see the front tarsi clearer than can be seen in these photos to be sure. Could I ask Piet & Gumenuk what features gave this away as arbustorum please? |

I would like to give a citation of Mark: Mostly just the look and feel from looking at 1000s of them.  No, in "nemorum" you have a very small/short pterostigma and in our case it is much too large. In most specimens of "nemorum" you have well defined triangle spots on tergite 2, sometimes you might have some bright color in anterior corners of T3 but the yellow color is never in such extention as our male is showing. Typical "nemorum" with short pt and in coloration: http://www.diptera.info/photogallery.php?photo_id=2055 Finally you have in arbustorum/abusiva those broad and white respectively yellow posterior margin of tergites. I'm sure that this specimen listed as interrupta in the gallery belongs to arbustorum/abusiva: ww.diptera.info/photogallery.php?photo_id=195 Regards Piet |

Hello Guys, The two features which lead to E. arbustorum is the stigma which is longer then wide and the mid-tibia has the top darkened. It's entirely white in E. abusiva. Greetings, Ectemnius |

Piet Nord - Thanks, good argument. Ectemnius - Too it is convincing. And what final conclusion? I am not able to make it - I only photograph :-( |

Conclusion still is arbustorum. abusiva is excluded by the first view on eyes meeting in a long distance. |
