I'm just back from a holiday in Switzerland. Marvellous mountains, with many robberflies! I hope this forum can ID the ones I photographed

This one I only saw at ca 1900 altitude, in half open coniferous woodland. They may rest on the mountain paths but more often I saw them on tree trunks. Medium sized for a robberfly, say ca 15 mm. The yellow bands are especially conspicuous is the fly lands and holds its wings open.

Although I'm not sure, I guess these are male and female - though I don't know what is the male, so that information would be useful too!

and the other sex

and here is the view when it has just landed but not yet closed its wings

It's Cyrtopogon ruficornis (male and female). Males have very uncommon front tarsi. Please add your images to Wikipedia: http://commons.wi...y:Asilidae - Thanks

Thanks for the quick reply! What's sp special about the male's front tarsi?


I'll do that, as well as to this site's gallery....

Please check the front tarsi on image one: they are elongated and narrow - very uncommon, but known from some other genera, too, like Leptarthrus. Yours
