Common on dry limestone grass-shrub vegetation above Lot valley at Cajarc (46160 France). Strange appearance in flight, because all you see are the two bright yellow patches, so that it appears quite a small insect. Not easy to approch when settled & it took some work with binoculars to figure that it was a Neuropteran. Wings fold back into triange, so that black patches form a continuous diamond patch. Nice image above!
