dear Dipterists, last weekend I spotted some flies on a sandy shore of an (artificial) sand pit (25 m wide, 2 m deep). apparently these belong to the Muscidae genus Lispe. is there anyone who can help me ID this pretty fly to species level? many thanx ..!

My guess is Lispe tentaculata female

I'm far from a expert, but aren't the fore tarsi predominantly yellow by the tentaculata ?? I thought is was the consanguinea....(because of the almost round palpi) Greatings Joke |

The fore-tarsi are yellow in the male tentaculata, but I don't think they are in the female. Palpi can look round or elongate depending on the angle at which they are viewed. I'm not sure that there's much difference in palpal shape between these two species. This picture may show consanguinea, but without a specimen (or picture of an associated male), it will be difficult to be sure. To me, it looks more like tentaculata than the pictures of consanguinea that I've seen. (I haven't got any specimens of consanguinea - it's a rare species here!)

many thanx Tony (and Joke). i read in Roskosny & Gregor (2004, p. 60) that in females 'Alle Tarsen schwarz, die Tibien koennen aber bei einige Individuen ausgedehnt gelb sein'. so apparently female tentaculata normally has black tarsi. i'll register it as a possible tentaculata. best wishes, David |
