Chrysopilus but not one I know. The only one recorded from Switzerland of which I completely am unaware of what it looks like it C. palparis.

Consulting Lindner in Lindner, I'd say it is the female of Ch. erythrophtalmus, which should occur in Switzerland. Theo |

Hmm, any pictures I could find for that species did not have those silvery markings, and none of the descriptions I have seen mention that. Still, I do not have Lindner to consult.

I'd agree with erythrophthalmus - the females have silver markings on the abdomen (see description and picture in Stubbs and Drake) - it is typically associated with mountain streams.

Paul, the point is, erythrophthalmus is strongly sexual dimorph. Theo |
