No, but close. The topcel has a longer petiole, which suggests Estheria in Dexiinae - Dexiini, as is Prosena. Prosena is easily recognized by the very long proboscis, that is, if you can have a look at the head ! Theo |

Thanks Theo Is it possible to identify the species ? I tried with your key but had a problem with the colour of the scutellum : it isn't completely red but not so dark, ... What's your opinion ? NB: Sorry for the private message but I confused PM=Private Message with Post Message.  ?ric |

Hi Eric, Under the assumption that the picture is taken in Central Europe (Belgium ?), the species is definitely Estheria cristata. Scutellum largely orange and dc 3+3 (though difficult to see). But, if it is taken in the Mediterrean, I cannot be sure. Greetings Theo |

Hi Eric, Do you have more information ? Estheria cristata has become extinct in The Netherlands somewhere around 1920 (!), so its occurence in Belgium is of interest Theo |

Hi Theo, I took this picture 23/7/2005 in the locality of Remouchamps, at the extreme east of the calcareous zone (excuse my bad english !). The fly was eating on flowers of Heracleum sphondylium in a path between a wet meadow (whith horses) and forest. Is this type of information you are waiting ? If not, what precision would be useful ? UTM coordinates ? Other plants or insects in the same place ? ... Thanks for your interest in my observation. ?ric |
